The elementary step reversible reaction shown below occurs in the liquid phase in a plug flow reactor. The feed contains only A at a concentration of 5 mol/L at a volumetric rate of 40 L/h. The reversible reaction is first order with rate constants k = 12.5 h and k2=5h-1 AB (a) Determine the reactor volume required for CA to reach 2 mol/L. (b) What is the maximum conversion of A that can be achieved? Determine the volume required to maximize conversion of A (production of B). Justify your answer.
