Consistent account of force correlations in a many-particle derivation of non-Markovian kinetic equations for chemical reactions in solutions

The previously proposed many-particle method for the derivation of kinetic equations of chemical reactions in liquid solutions is applied to the consideration of irreversible reaction A+B→C+B. Both force and chemical space correlations resulting from the force interactions between all reactants and chemical reaction between A and B species are taken into account on the same basis. Examination of chemical and force interactions in the system of reactants shows that their contributions to the time evolution of correlation patterns differ essentially because of different analytical properties of the above interactions. It is shown that proper account of the force interaction between reactants corresponds to the change in the character of a relative mobility in the ultimate evolution of a reaction pair (ultimate propagator), not only in the process of correlation accumulation in effective pairs, as is sometimes assumed.
