Chemical Thermodynamics And Kinetics

[Francoise Witsell]

Canteraautomates the chemical kinetic, thermodynamic, and transport calculations so that the users can efficiently incorporate detailed chemical thermo-kinetics and transport models into their calculations.

Cantera utilizes object-oriented concepts for robust yet flexible phase models, and algorithms are generalized so that users can explore different phase models with minimal changes to their overall code.

Cantera is currently used for applications including combustion, detonations, electrochemical energy conversion and storage, fuel cells, batteries, aqueous electrolyte solutions, plasmas, and thin film deposition.

Cantera is developed by a team of volunteers, and we're always looking for new team members. If there is a feature you want added, a bug that needs to be fixed, or even just a typo in the documentation, changes from the community are always welcome.

The first thing my kinetics textbook demonstrated was how thermodynamics ignores time taken for a process whereas kinetics considers the time and rate of the process and hence kinetics is a more effective way to view change.

Also, I saw examples of highly thermodynamically feasible reactions which were not kinetically favourable in the sense that they were so slow that the entire process could be neglected as not happening.

No. Both I think are equally theoritical or experimental. You must study both seperately. Thermodynamics doesn't speak about rates. While kinetics doesn't tell you stability. If a reaction produces more than one product, thermodynamics will tell you which is more stable, while that doesn't necessarily mean it is the major product. It may happen that rate of formation of other product is more under certain conditionds. Read about thermodynamic vs kinetic product and you will get it.

A one-term chemistry course designed for non-science majors. In this course we examine what gives rise to three-dimensional shapes of molecules and we explore how the structure and composition of molecules gives rise to chemical reactivity. Our goal is to understand readily observable phenomena (e.g. removal of grease by soap, storage of toxins in fat tissues, cancer, viruses, etc.). Topics include those of current global interest such as anthropogenic forces on the environment and energy producing technologies. The course includes one four-hour lab per week.

An introduction to the fundamentals of chemistry to prepare students to enter subsequent chemistry courses (Chemistry 123 or 128). Atoms and molecules, stoichiometry, and gases will be covered in the course. Although learning through discovery-based processes, small groups, and short laboratory experimentation will occur, this is not a lab course and does not fulfill the requirements for medical school. This course assumes competence with simple algebra, but no prior chemistry experience.

An introduction to chemistry for students who have strong high school preparation in chemistry or who have taken Chemistry 122. Topics include the electronic structure of atoms, periodicity, molecular geometry, thermodynamics, bonding, equilibrium, reaction kinetics, and acids and bases. Each offering will also focus on a special topic(s) selected by the instructor. Students cannot receive credit for both Chemistry 123 and 128.

A more advanced study of several core introductory chemistry principles. This course is suitable for students with advanced placement in chemistry or students who have completed Chemistry 123 or 128. Topics include coordination chemistry, advanced bonding models, spectroscopy, advanced acid/base and redox equilibria, and electrochemistry. The topics will be taught from varying perspectives using examples from biochemistry, the environment, energy, or materials chemistry. The lab will focus on developing computational, quantitative, and synthetic skills and will prepare students for more advanced laboratory work in chemistry.

Theoretical aspects of carbon chemistry are examined with reference to structure-reactivity relationships, functional groups, stereochemistry, reaction mechanisms and spectroscopy. Laboratory work concentrates on modern techniques of organic chemistry, inquiry-based projects, and spectroscopic analysis. One laboratory per week.

The chemistry of functional groups is continued from Chemistry 233, and is extended to the multifunctional compounds found in nature, in particular carbohydrates and proteins. The laboratory focuses upon inquiry-based projects and spectroscopic analysis. One laboratory per week.

A mixed class/lab course with one four-hour laboratory per week and weekly discussion/problem sessions. In class, the principles of kinetics will be developed with a mechanistic focus. In lab, experimental design and extensive independent project work will be emphasized.

This combined lecture and lab course teaches students how to use modern spectrometric techniques for the structural characterization of molecules. Lectures will cover topics and problems in the theory and practical applications associated with GC-Mass Spectrometry, ESI-Mass Spectrometry, Infrared, and Nuclear Magnetic Resonance Spectroscopy (1H, 13C, and 2D experiments). Students will apply all of these techniques in the laboratory for the structural characterization of known and unknown molecules.

This course involves the natural extension of the principles of chemistry to biological systems. The topics to be examined center around the biochemical formation and cleavage of chemical bonds, with an emphasis on the structure and function of the proteins that mediate these processes.

Purification and characterization of proteins and nucleic acids, with a focus on enzyme kinetics and mechanism, macromolecular interactions with small molecules and the basis of specificity in biological systems. One laboratory per week.

This course covers the basic principles of quantitative instrumental chemical analysis. Course topics include chromatography, electroanalytical chemistry, analytical spectroscopy, and mass spectrometry. The background needed to understand the theory and application of these instrumental techniques will be covered. In addition, students will have the opportunity to explore current research in the field of analytical chemistry through the reading and presentation of articles from the primary literature.

This laboratory provides students with experience in using instrumental methods for quantitative chemical analysis. Laboratory work consists of several assigned experiments that use instrumental techniques such as liquid and gas chromatography, UV spectrophotometry and fluorometry, mass spectrometry, and voltammetry. This laboratory concludes with an instrumental analysis project that is researched and designed by student groups.

This laboratory introduces students to the general components that make up an instrument used for chemical analysis. These components include transducers, analog and digital electronic components, data transmission hardware, computers, and appropriate software. The specific topics to be covered are ion selective electrodes, fluorometry, analog electronics, basic data acquisition principles, serial data communication, Arduino and LabVIEW programming.

The major topic is chemical thermodynamics, including the First and Second Laws, the conditions for spontaneous change, thermochemistry, and chemical equilibrium. To showcase how chemists utilize energy concepts to solve problems, thermodynamics will be regularly applied to a number of real-world examples and scientific problems.

This course introduces quantum mechanics with an emphasis on chemical and spectroscopic applications. The focus will be on atomic and molecular quantum behavior involving electrons, rotations, and vibrations. The objective is to develop both a deeper understanding of bonding as well as an appreciation of how spectroscopy provides insight into the microscopic world of molecules.

This class will introduce students to computational chemistry with a focus on simulations in chemistry and biology. This course will include hands-on experience in running classical molecular dynamics and quantum chemistry programs, an introduction to methods to simulate large systems, and demonstrations of the use of more sophisticated software to simulate chemical and biological processes. It will also include a survey of the current literature in this area, as well as lecture time in which the background necessary to appreciate this growing area of chemistry will be provided.

Symmetry, molecular orbital theory and ligand field theory will provide a framework to explore the bonding, magnetism and spectroscopic properties of coordination complexes. Topics in reactivity (hard and soft acids and bases), bioinorganic chemistry, reaction mechanisms, and organometallic chemistry, will also be introduced.

This course explores the relationship between structure and reactivity in organic molecular systems, with an emphasis on reaction mechanisms. Topics include molecular orbital theory, stereoelectronic effects, linear free energy relationships, and kinetic isotope effects. We will use these theories to revisit and deepen our understanding of reactions from Chemistry 233 (Organic Chemistry & Lab) and 234 (Organic Chemistry II & Lab). We will then analyze additional classes of reactions, such as pericyclic, enantioselective, and organometallic transformations. Students will use the primary literature to further investigate these topics.
