Notes:
A simple model is devised for the diffusion mediated reaction of an asymmetric molecule with ambient reactants. For the particular model in which the surface reactivity is assumed to vary as 1+β cos θ, where θ is the polar angle and 0≤β≤1, an analytic solution in the form of an infinite continued fraction was obtained for the steady state reaction rate. This fills a gap in the theory of reaction rates of asymmetric molecules which generally have been investigated by numerical computation. In agreement with previous studies on other models with smoothly varying reactivity, it is found that the steady state reaction rate depends primarily on the surface averaged reactivity. The effect due to asymmetry is only of secondary importance for such models and even this tends to get washed out as the rotational diffusion coefficient increases.
