Problem 1: Elements of Chemical Reaction Engineering 6h Ed. P5-9 (a-d) P5-9, DEQ (Old Exam Question). The liquid-phase reaction A+B-C 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 2 M before mixing. The volumetric flow rate of each stream is 5 dm?/min, and the entering temperature is 300 K. The streams are mixed immediately before entering. Two reactors are available. One is a gray, 200.0-dm CSTR that can be heated to 77C or cooled to O*C, and the other is a white, 800.0-dm PFR operated at 300 K that cannot be heated or cooled but can be painted red or black. Note that k = 0.07 dm /mol min at 300 K and E = 20 kcal/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 200-dm batch reactor with CA = Co- 1 M after mixing at a temperature of 77C? c. What would your answer to part (b) be if the reactor were cooled to 0C? (Ans: 2.5 days) d. What conversion would be obtained if the CSTR and PFR were operated at 300 K and connected in series? In parallel with 5 mol/min to each
