Abstract

We evaluate a rigorous lower bound on the rate constant k associated with diffusion-controlled reactions in a porous medium composed of impenetrable spherical sinks, for a wide range of sink volume fractions. The results are compared to an effective-medium approximation for k. It is found that the lower bound gives a useful estimate of the rate constant for virtually all sink concentrations.
