Consider the irreversible conversion of species A to B in a stationary liquid film of thickness L, as shown in the figure below. Determine CA throughout the film, if the surface at y=0 is assumed to be impermeable and unreactive, and the concentration of A at y=L is specified as C0. The homogeneous reaction follows zeroth order kinetics, with RA=KH. Also, find the overall rate of product formation. Steady diffusion in a liquid film with an irreversible homogeneous reaction
