Enthalpy is the heat content of a system. As we all know, the heat can go in or out of the system. If this system is a chemical reaction, the change of heat is called enthalpy change. Knowing if the enthalpy of the system increases or decreases,during a chemical reaction is a crucial factor to understand if that reaction can happen.The change in the enthalpy of the system during a chemical reaction is defined as the change in its internal energy plus the change in the product of the pressure times the volume of the system:

Entropy refers to the measure of the level of disorder in a thermodynamic system. It is measured as joules per kelvin (J/K) and denoted by the symbol 'S'. For any spontaneous process, the entropy of the system should increase. Entropy is calculated in terms of change as well and defined with the following formula:

Ludwig Boltzmann defines entropy as the measure of the number of possible microscopic configurations of the atoms and molecules in accordance with the macroscopic state of the system. It can be described with the following equation:

Based on this definition, solids have lowest entropy due to their more regular crystalline structure; liquids have an intermediate entropy as they are more ordered than gas but less ordered than solids; Gases are known to have the highest entropy as they have the most disorder.

Gibbs Free Energy is used to measure the amount of available energy that a chemical reaction provides. As reactions are usually temperature dependent, and sometimes work significantly better at some temperatures than others, the ΔGf values known are only valid at 25C (298.15 K).

It's important to note that spontaneous does not necessarily mean that the specific reaction proceeds at high rate. A spontaneous reaction can take ages to go to completion. A classic example is the rusting of metal.

Going back to enthalpy and entropy, we can define the relationships between these two values, correlating them with the Gibbs free energy. For all temperatures, including 25C, the following equation can be used to determine spontaneity of a chemical reaction:

The value calculated for ΔG is considered an approximate, especially as the temperature moves further away from 25C as both ΔH and ΔS will vary with temperature. A change of ΔS will impact ΔG tends less. This is because ΔS is measured in units of J/K and when converted to kJ/K it is numerically small. A small change of ΔH but can have a great impact on ΔG.

It can be difficult to keep your notes organized throughout the school year, especially in a class that covers so much content. This article will give you links to notes on every topic included in the AP Chemistry curriculum. If you're missing some of your notes, or if you just want a more structured overview of what you need to know for the exam, you've come to the right place! We'll also give you some study tips so that you can use both these notes and the notes you took throughout the year to your best advantage.

The notes in this article can be used to study smaller portions of the curriculum or to review for the final AP Chemistry exam. There are currently nine units that organize all the concepts in the course, so we've categorized these notes according to that framework. Topics should be listed in roughly the same order as you learned them in class.

These notes will provide a ton of background information, but keep in mind that AP Chemistry is less about memorization of facts and more about the ability to apply your knowledge to a variety of experimental scenarios. Reading notes can only get you so far. Practice problems are essential (a point that I will emphasize again later in this article).

Take a diagnostic test before you dive into these notes if you plan on using them to review for the full AP test. Based on your results, you can see which areas need the most improvement, and then you can focus on the notes that are most relevant.

These notes come from several sources. Some are in-depth, others give a broad overview. Some are in-depth, others give a broad overview. Some focus more on explaining concepts, others on working through practice questions. The overall goal of these notes is to give you a comprehensive guide of what you need to know for AP Chemistry.

If you want to use these notes to your full advantage, you shouldn't just read them all and consider yourself prepared. For chemistry, you need to dig deeper to understand the material fully. That said, here are some tips to keep in mind:

If you're studying for chemistry, you should work your way through concepts in the order of when they show up in the curriculum. You need to master the basics first, or more advanced problems will look like complete gibberish to you. If there are any topics in Unit 1 that you don't feel comfortable with, start your studying with those. Everything else in the course builds on the concepts you learned in the first couple of months!

Every time you read a set of notes, do a few practice problems to make sure you've absorbed the information. Reading through these notes is a waste of time if they don't provide you with the background information and skills you need to solve relevant problems. If you find that you're having trouble with practice problems after you read through notes, this should be a red flag that you need to modify your study strategy.

Don't forget about the notes you took in class, handouts your teacher gave to you, and any other resources you've accumulated throughout the year. It's worthwhile to shop around and see whether certain explanations of concepts resonate more than others. You might decide that videos explaining concepts are more useful to you than notes, or you may choose to buy a review book that provides more guidance in planning out your studying.

It's unwise to cram for AP Chemistry. You need to do plenty of practice problems to feel comfortable with the material, and, if you cram, you won't be able to spend enough time on this. Don't pull out your notes the day before the exam and expect to learn everything in one marathon study session. You won't retain the information, and you'll be exhausted for the test.

The notes in this article should help you review all the essential concepts you need to know for the AP Chemistry exam. Make sure you supplement your review with practice tests so you can assess your progress and see where your main strengths and weaknesses lie. Also, keep in mind the tips we went through in the last section:

Notes are all well and good, but when do you actually need to start using them to review for the test? Find out how early you should start studying for AP exams if you're aiming for a great score.
