(15 pts) The gas phase, second order reaction A B is performed in a PBR under isothermal conditions. The feed enters the PBR at 5 L/hr and contains 0.2 mol/L of A. The reaction rate constant is k = 1 L2/(mol kg - catalyst.hr). a. Assuming no pressure drop, what is the weight of catalyst needed to reach an 80% conversion of A? b. Assuming there is pressure drop, what is the weight of catalyst when the outlet pressure is half of the inlet pressure? a = 0.0015 What is the conversion of A under the condition in part b? C
