Consider the following liquid phase series reactions, which are both first order. k k2 A B C The feed to a non-isothermal CSTR contains pure A at 250C with a concentration of 6.25 mol/L. We wish to operate the reactor such that the product stream has a concentration ratio of B to C of 10 with a 50% overall conversion of A. Other relevant data is given below. The reactor is operated at steady state. v = 8 L/sec mt = 9.0 kg/s (total mass feed flow rate) k = 2.0 x 10 exp(-31,000 cal/mol / RT) sec-1 k2 = 4.0 x 1011 exp(-40,000 cal/mol /RT) sec-1 = AH1 -5,000 cal/mol AH2 -15,000 cal/mol = Cp 0.18 cal/g-K R 2 cal/K-mol (universal gas constant) a. Perform the necessary material balances and determine the operating temperature of the reactor to achieve the above-mentioned conditions. b. What is the volume of the reactor to achieve the desired product stream? c. What is the necessary rate of heat transfer to the surroundings?
