A many-particle treatment of the reversible reaction A+B double left rightarrow C+B

A many-particle consideration of diffusion-influenced reversible pseudo-fir st order reaction A + B reversible arrow C + B is presented. It is shown th at the lowest order (in concentration) of the memory matrix is not sufficie nt for describing the binary kinetics of the reaction. Binary kinetic equat ions describing both stationary and nonstationary stages of the kinetics ha ve been obtained using diagrammatic representation and selecting the necess ary diagrams. Comparison with the fully renormalized kinetic theory is made by considering the contact approximation for reactivity. (C) 1999 American Institute of Physics. [S0021-9606(99)51119-7].
