We have following series reactions which are taking place in a membrane reactor.

It has been found that the pressure drop varies as (dp)/(dV ) , (= p /V2 p)(F_t/ F_to) where = 10^-3 m^ -3 . The total concentration entering the reactor is 0.1 mol/m3 and entering volumetric flow rate is 100 m 3 /min. In this membrane reactor, species C diffuses out of the reactor with the transport coefficient kC = 10 min-1 . (35 Pts) (a) What are the net rates of formation of A, B, C, D, and E? (b) Plot molar flow rates of A, B, C, D, E and p as a function of a reactor volume up to V = 800 m 3 and comment what you obtain. (c) In this reaction, species D is a desirable product and E is an undesirable product. If you need to obtain as much as species D, which volume of reactor would you choose? Also, if the purity of D in your final product is more important, which volume of reactor would you choose?

AB+C, with r1A=k1ACA, where k1A=0.6min1 A+3CD, with r2D=k2DCC2CA, where k2D=300m6/(mol2min) C+2DE, with r3E=k3ECDCC, where k3E=20m3/(molmin)
