2. (50 points) A 150L plug flow reactor has been designed for the second order irreversible constant density reaction 2AC. Because of expected difficulties in operating the plug flow reactor ideally, the reactor has been modeled as a 25L CSTR flowed by a 125L plug flow reactor. With CAO=17Lgmole and k=0.3gmoleminL, the overall conversion, XA, in the model system is 92%. a. Explain why the two reactor system (small CSTR followed by a larger plug flow reactor) can be a good representation of the performance of the 150L plug flow reactor. b. What is the flow rate, v0, through the 25L CSTR/ 125L plug flow model reactor system? 60.9L/min c. If the original plug flow reactor operated ideally as designed, what is the conversion in this reactor, XA at the flow rate, v0, calculated in part b ? XA=0.92L d. If the model CSTR and plug flow reactors were reversed (125L plug flow reactor followed by the 25 L CSTR), would the flow rate, v0, be greater than or less than the flow rate in the original 25L CSTR/ 125L plug flow model system? Note that there is no need to do calculations to answer this question. V0 is increas to 65.1L
