The first-order, gas-phase, reversible reaction, 3 + is carried out in a IMCRF with no pressure drop. Pure A enters the reactor, and C diffuses through the membrane.

a. Would the conversion of A be greater or smaller if B were diffusing out instead of C?

b. Would the conversion of A be greater or smaller if a small amount of A and a moderate amount of B were diffusing out instead of C?

c. Qualitatively how would the profiles of FA, FB, FC, and X as a function of the catalyst mass, W, change if there was significant pressure drop in the packed-bed?
