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 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 77°C 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, long would it take to achieve
