The liquid phase reaction A-RA-R is taking place in an ideal batch reactor. The reaction is homogeneous and irreversible, and the rate equation for the disappearance of A is -rA=k(CA)^2 At 150 C, the value of k is 7.60 L mol-1 h-17.60 L mol-1 h-1. The enthalpy change on reaction, AHR, is -37.5 kcal/mol A at 150 C. The initial concentration of A is 0.65 mol/L. The reactor is to be kept isothermal at 150 C over the whole course of the reaction. Cooling water is available at 30 C at a flow rate of 6000 kg/h. If the reactor volume is 1000 L and the overall heat-transfer coefficient is 500 kcal m-2 h-1 C-1, how much heat-transfer area must be installed in the reactor? The highest rate of heat generation will be when the reactant concentration is the highest, that is, at t=0. Use this heat load to determine the required area of heat transfer.
