What PFR volume must be added to the first CSTR (part b) to raise the conversion to 80%? e. What conversion can be achieved in a 6 x 104 m³ PFR? 5. The liquid phase reaction, A + B C follows an elementary rate law and is carried out isothermally in a flow system. The concentrations of 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 dm' CSTR that can be heated to 77°C or cooled to 0°C, and the other is a white 800 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. (4,2) you recommend? Explain the reason for your choice (color, a. Which…
