Consider the first-order gas phase reaction (A B) taking place on the inner surface of a straight cylindrical catalyst pore. Assume that the catalytic reaction is the first order with a rate constant k". See the figure below. Note that only one end of the pore is open. Open end Closed end CA = CAS z = 0 Z=L (A) Determine the concentration profile of A within the pore as a function of z, L, k", De (internal effective diffusivity), ro (the radius of pore) and CAS 200
