Excluded Volume Effect on the Diffusion-Influenced Bimolecular Reactions

By applying the reduced distribution function approach to the diffusion-influenced bimolecular reaction, we evaluate the effect of excluded volume between nonreacting like molecules on the transient kinetics. It is found that concentrations of reactant molecules decay more rapidly with the excluded volume taken into account than without it. Comparison with previous works dealing with the excluded volume effect shows a qualitative agreement, but it appears that previous works underestimate the excluded volume effect.
