The influence of relative motion peculiarities of reactants in solutions on the rate of physico-chemical processes

The quasistationary rate constant of irreversible reactions of the type of trapping by diffusing traps excitations, electrons or particles migrating by stochastic jumps of arbitrary length in condensed matters has been calculated. It has been shown that the two-scaled nature of the relative translational mobility in reactions proceeding near the contact of reactants gives rise to new kinematic mechanisms of such reactions. These mechanisms are characterized by unusual dependence of the reaction rate constant on microscopic parameters.
