P5-9 A OEQ (Old Exam Question). The liquid-phase reaction A+BC follows an elementary rate law and is carried out isothermally in a flow system. The concentrations of the A and B feed streams are each 2M before mixing. The volumetric flow rate of each stream is 5dm3/min, and the entering temperature is 300K. The streams are mixed immediately before entering. Two reactors are available. One is a gray, 200.0-d m3CSTR that can be heated to 77C or cooled to 0C, and the other is a white, 800.0-dm 3 PFR operated at 300K that cannot be heated or cooled but can be painted red or blackNote that k=0.07dm3/mol ' min at 300K and E=20kcal/mol. a. Which reactor and what conditions do you recommend? Explain the reason for your choice (e.g., color, cost, space available, weather conditions). Back up your reasoning with the appropriate calculations. b. How long would it take to achieve 90% conversion in a 200dm3 batch reactor with CA0=CB=1M after mixing at a temperature of 77C
