2. A first-order reaction; is to be carried out in two adiabatic PFR reactors in series. The temperature of the stream at the exit of the first reactor is 340C. The concentration of the reactant A which enters the first reactor is 1 mol/m and the inlet volumetric flowrate is 10 m/h. Schematic diagram and the related data are given below. AH R = -15000 cal/mol CPA CPB 42 cal/mol. C k = 110+ 0.8 (T-200) h (T in C) A B a) Calculate the volume of the second reactor required in order to obtain 70% conversion of A at the exit? b) Calculate the temperature of the exit stream (T2) for the second reactor?
