The liquid-phase reaction A + 2B C + D is conducted in a CSTR. The reaction kinetics are first-order in both A and B with a rate constant k_A = 0.17 L/mol-min. The feed is equimolar at C_A0 = C_B0 = 0.80 mol/L, and the inlet volumetric flow rate is 18 L/min. The molar flow rate of the solvent is 720 mol/min. The reactor temperature is to be held at 350 K.

What reactor volume is needed to achieve an outlet flow rate of C of 4.5 mol/min?

The reactor feed is at a temperature of 300 K. To maintain the reactor temperature at 350 K, will the reactor need to be heater or will it need to be cooled? At what rate must heat be added to or removed from the reactor?

Some additional data: (Values may be considered constant over the temperature range from 300-400 K) H_rxn = -24 kcal/mol, C_P,A = C_P,B = 74 cal/mol-K, C_P,solvent = 40 cal/mol-K
