Hi
Is there a way using LaTeX to place rate constants above the arrows in chemical
equations? Example:

k=rate const.
A + B -----------------> C


Replies by post or mail appreciated.

Thanks,

The AMS LaTeX packages have an \xrightarrow[below the arrow]{over the arrow}
command; and then there are chemic-specific packages (like ppchTeX and chemic),
but I believe these are mainly oriented on typesetting other aspects of the
formulas.

AMS-LaTeX provides extensible arrows. However, for similar tasks I use
Paul Taylor's diagrams, a light-weight diagram package. That's because
I often need more 'elaborate' arrows and it lets me customize them a
lot (and in any case I need it for 'real' diagrams).

The following bit has worked for me. The first one has rate constants
above and below an equilibium arrow, the second equation only has one
above an arrow. I have since started using the chemsym package so
that i don't have to use \mathrm on the chemical symbols}


\usepackage{amsmath}
...

\begin{eqnarray}
\mathrm{CO(gas)} &\overset{k_1}{\underset{k_2}{\rightleftharpoons}}&
\mathrm{CO}^* \\

\mathrm{CO}^* +\mathrm{O}^* &\stackrel{k_3}{\rightarrow}&
\mathrm{CO_2} + Q_{heat}
\end{eqnarray}
