EXACTLY SOLVABLE MODELS IN THE THEORY OF IRREVERSIBLE REACTIONS IN LIQUIDS

Exact kinetic equations defining the A + B --> B reaction in liquid so lutions are obtained on the basis of a many-particle approach and the notion of point-reacting particles with remote reactivity. For any ini tial correlations in the system of reactants, the calculation of many- particle kinetics is shown to reduce to the calculation of survival pr obability of one particle A in the ensemble of particles B. In the con text of the most general model the exact equations in the thermodynami c limit are obtained. The equations define the process which develops from two classes of initial correlations: those of the same type corre sponding to the reactions in the bulk, and polytypic correlations corr esponding to the reactions in non-isolated geminate pairs.
