KINETICS OF DIFFUSION-INFLUENCED REVERSIBLE-REACTION A-REVERSIBLE-ARROW-C IN SOLUTIONS(B)

Reversible diffusion-influenced pseudo first order reaction A+B revers ible arrow C with static particles in excess is rigorously studied. Un der most general assumptions, the problem of the reversible reaction k inetics is reduced to the consideration of the effective irreversible reaction studied by conventional methods. In the framework of the aver age t-matrix approximation (ATA) we reproduce some results derived ear lier and establish their applicability limits. Rigorous investigation of the kinetics behavior at long times shows that the t(-3/2) law pred icted earlier and reproduced by ATA has a different concentration-depe ndent amplitude. On the basis of diagrammatic summation, providing cor rect long-time asymptotics, a modified theory has been developed. The range of validity of the modified theory is much wider than that of AT A and similar theories. (C) 1995 American Institute Of Physics.
