We report three-dimensional simulations of the reversible reaction A BC for a single static A
molecule and a uniform initial concentration of noninteracting B-molecules. The results are
compared with various analytic approximations for the time-dependence of the binding probability.
They are in excellent agreement with a recent theory of Sung and Lee J. Chem. Phys. 111, 796
1999 for all times and rate parameters. The second-order term in the long-time expansion of this
theory is incorrect, yet it explains an apparent kinetic transition observed when the B-concentration
increases. We also investigate the concentration profiles near the reversible trap. 2001 American

I. INTRODUCTION
Bimolecular reactivity is a many-body problem. This has
been recognized early on by Smoluchowski,1
who has ob-
tained the survival probability, Sirr(t), of a static target mol-
