II. Numerical problems (70 points) 1. (35 points) Consider an irreversible, liquid-phase, elementary reaction 2A B carried out in two continuous stirred tank reactors (CSTRS) in series. The two reactors have the same volume. The intermediate conversion of A exiting the first reactor prior to entering the second reactor is 50%. Assume that the volumetric flow rate remains constant throughout the process. (A) (5 points) Write down the rate law describing the rate of disappearance of A (i.e..-TA) in terms of the rate constant (k), the conversion of A (X), and the initial concentration of A (CAD). (B) (15 points) Calculate the value of the Damkhler's number for the operation. (C) (15 points) Determine the final conversion of A after the second reactor.
