The problem of diffusion among mixtures of different partially absorping traps was investigated. The choice of the problem was motivated by a variety of biological phenomena including the consumption of nutrients by cells and the study of magnetic relaxation in tissues. The trapping problem involved diffusion which took place exterior to a collection of fixed traps with reaction occuring at the surface. The overall trapping rate for systems of partially absorbing spherical traps was predicted using a simulation technique. A single, universal curve was obtained for accurate predictions of effective surface rate constants over a wide range of trap volume fractions and different trap distributions.
