The elementary irreversible liquid-phase reaction

A + 2B → C

is to be carried out in a semibatch reactor in which B is fed to A. The volume of A in the reactor is 10 dm3, the initial concentration of A in the reactor is 5 mol/dm3, and the initial temperature in the reactor is 27 °C. Species B is fed at a temperature of 52 °C and a concentration of 4 M. It is desired to obtain at least 80% conversion of A in as short a time as possible, but at the same time the temperature of the reactor must not rise above 130 °C. You should try to make approximately 120 mol of C in a 24-hour clay allowing for 30 minutes to empty and fill the reactor between each batch. The coolant flow rate through the reactor is 2000 mol/min. There is a heat exchanger in the reactor.

(a) What volumetric feed rate (dm3/min) do you recommend?

(b) How would your answer or strategy change if the maximum coolant rale dropped to 200 mol/min? To 20 mol/min?
