The compensation effect in activation processes from the point of view of statistical kinetics

Part 2. Possible physical causes for the appearance of the compensation effect in certain systems and processes

  • Published:
Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Summary

  1. 1.

    An explanation has been given of some general stastico-kinetic causes, leading to a strong dependence of the preexponential factor in formulas for the rate of activation processes on the activation energy, and the corresponding formulas have been derived.

  2. 2.

    It has been shown that because of the localization of the overwhelming majority of elementary acts of the activation processes in macroscopically small regions possessing “instantaneous” temperature considerably in excess of the mean temperature of the system, and depending on the activation energy, in the expressions for the rate constant a strong relationship is revealed between the preexponential factor and the activation energy. Conditions typical for condensed systems have been established, which favor the appearance of a considerable preexponential factor.
