An isomerization reaction has the simple form A →B. Assuming that operating conditions and the condition of the catalyst are such that the external- and internal-diffusion steps have negligible concentration gradients, propose rate equations for the following cases: (a) The adsorption of A on the catalyst is controlling. (b) The surface interaction between adsorbed A and an adjacent vacant center is controlling. (c) The desorption of B from the surface is controlling. In all cases the mechanism

the isomerization reaction ch3nc ch3cn is first order and the rate constant is equal to 046s 1 at 600 k what is the concentration of ch3nc after 020 minutes if the initial concentration is 0 19077
