. 2. (50 points) A 150 L plug flow reactor has been designed for the second order irreversible constant density reaction 2A C. Because of expected difficulties in operating the plug flow reactor ideally, the reactor has been modeled as a 25 L CSTR flowed by a 125 L plug flow reactor. With C17 gmole L and k = 0.3 the overall conversion, X in the model system is 2 gmole min 92% a. Explain why the two reactor system (small OSTR followed by a larger plug flow reactor) can be a good representation of the performance of the 150 L plug flow reactor. b. What is the flow rate, Vo, through the 25 LCSTR/125 L plug flow model reactor system? C0.9 min c. If the original plug flow reactor operated ideally as designed, what is the conversion In this reactor, Xe at the flow rate, Yo, calculated in part b? X 0.924 d. If the model STR and plug flow reactors were reversed (125L plug flow reactor followed by the 25 LCSTR), would the flow rate, V., be greater than or less than the flow rate in the original 25 L CSTR/125 L plug flow model system? Note that there is no need to do calculations to answer this question. Vo is it cream to 6.1L/min
