Ammonia is being cracked on a solid catalyst according to the reaction 2NH3N2+3H2 At one place in the system, where the pressure is 1 atm and the temperature 200C, the analysis of the bulk gas is 33.33%NH3(A),16.67%N2(B), and 50.00%H2(C) by volume. The circumstances are such that NH3 diffuses from the bulk-gas stream to the catalyst surface, and the products of the reaction diffuse back, as if by molecular diffusion through a gas film 1mm thick. Estimate the diffusion rate in kgNH/NH3/(m2 catalyst surface sec) if the reaction is diffusioncontrolled (i.e., chemical reaction rate very fast). Additional data: diffusion coefficient of NH3 in the gas mixture is approximately 104m2s1 at 200C. Show a detailed schematic, a list of at least five assumptions made, and all equations and necessary derivations to obtain an appropriate phenomenological model
