Abstract

According to the theory of chemical kinetics, the chemical reaction represented by

$$A\, + B\, + \, \cdots \, \mathbin{\lower.3ex\hbox{$\buildrel\textstyle\rightarrow\over {\smash{\leftarrow}\vphantom{_{\vbox to.5ex{\vss}}}}$}} \,M\, + \,N\, + \, \cdots \, + \,Q$$

can proceed in both directions, with respective rates, \(\vec \upsilon \) and \(\mathord{\buildrel{\lower3pt\hbox{$\scriptscriptstyle\leftarrow$}}\over \upsilon } \). The overall reaction rate υ, which can be determined directly by experiment, is shown by a difference:

$$\upsilon \, = \,\vec \upsilon \, - \,\mathord{\buildrel{\lower3pt\hbox{$\scriptscriptstyle\leftarrow$}}\over \upsilon } $$

Thus, the reaction may proceed in the right-hand direction (the forward direction) preferentially, if \(\vec \upsilon \,\, > \mathord{\buildrel{\lower3pt\hbox{$\scriptscriptstyle\leftarrow$}}\over \upsilon } \). Here Q represents the formation energy of the species located on the right-hand side of the reaction.
