COMPETITIVE DIFFUSION INTO 2 SINKS WITH A FINITE SURFACE-REACTION COEFFICIENT

The asymptotic solution for the reaction rate of two identical spheric al sinks of radius p with a surface reaction rate coefficient k, place d in an infinite medium of diffusivity D, is presented for mid to high surface reaction rates, i.e., 1 < lambda(-1) = k rho/D < infinity. Th ese results are then discussed in the context of the complete kinetic problem from chemical, lambda(-1) approximate to 0.1, to diffusion con trol, lambda(-1) --> infinity.
