(35 pts.) The reversible gas-phase reaction (forward and reverse reactions are elementary), AB is processed in an adiabatic CSTR. The inlet consists of pure A at a temperature of 100 C, a pressure of 1 bar and volumetric flowrate of 310 liters/min. Pressure drop across the reactor can be neglected. The following information is given: Kforward (25 C) = 0.02 hr Kc(25 C) 60,000 Ea = 40 kJ/mol AH.(100 C) - 50 kJ/mol Cp.A Cp.B 150 J/mol K (heat capacities may be assumed to be constant over the temperature range of interest) (a) (10 pts.) Calculate the exit temperature if the measured exit conversion, XA was 60% (35 pts.)
