Empirical rate equation for association reactions and ion–molecule reactions

Temperature dependence of the rate constants of many association reactions is now available. In order to express the rate constants at temperatures from very low to high, we tried to use the sum of new empirical rate equations for association reactions and Arrhenius equations. Temperature dependence of a number of radical–molecule and some ion–molecule reactions could be successfully demonstrated. A new procedure to analyze ion–molecule reactions was proposed. This might suggest a new viewpoint to understanding chemical reactions.
