Design a continuous stirred-tank reactor (CSTR) for the exothermic reaction of A + B → C with a rate constant of 0.05 L/mol/min. The reactor should produce a minimum of 500 g of C per minute, while maintaining a conversion of at least 90%. The feedstream of A and B is available with a flow rate of 2 L/min and an initial concentration of 1 M for both reactants. The reactor should be operated at a temperature of 50°C and a pressure of 1 atm. What should be the volume of the CSTR and the flow rate of the cooling medium used to maintain the desired temperature?
