Summary

  1. 1.

    Analysis of the experimental data provides a basis for the supposition that general causes exist which give rise to the profound relationship between the pre-exponential factor and the activation energy. This relationship does not emerge from the theory of absolute reaction rates and the assumptions of Frenkel', which do not take into account the collective character of the movement of interacting particles in a condensed system.

  2. 2.

    Taking account of the collective character of the movement of the particles in a condensed system during the consideration of the elementary act, leads to an exponential relationship between the pre-exponential factor and the activation energy. Analysis of the premises lying at the basis of the relationships obtained, reveals certain possibilities for further communications.
