An elementary reaction A+B C+D is to be carried out in a non-ideal CSTR which has both bypassing and a stagnant region in this reactor. The measured reactor volume is 1.0 m3 and the flow rate to the reactor is 0.1 m3/min. The reaction rate constant is 0.28 m3/kmol.min. The feed is equimolar in A and B with an entering concentration of A equal to 2.0 kmol/m3 k. Calculate the conversion that can be expected in this reactor if the model parameters of α and β were determined from a tracer test and were found to be 0.8 and 0.3 respectively.

heat exchanger jacketing the reactor. The flowrate of coolant
through the jacket is sufficiently high so that the ambient
exchanger temperature is constant at 50oC.
