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?

Calculate the potential difference between two silver electrodes that are placed into a solution containing 0.1M of AgNO3 and a current of 2.5 A is passed through the cell. The polarization caused by the passage of current through the cell is found to be 0.2 V. Given that the standard reduction potential of Ag+ to Ag is 0.80 V, calculate the equilibrium potential of the cell.
