4 Opolts A second-order liquid-phase reaction A * B is carried out isothermally at a temperature of 360K in a flow reactor (non-ideal reactor). Pure A enters the flow reactor with an initial concentration of 2 mol dm? The specific reaction rate constant k at a temperature of 310K is 0.35 am mol 1 min. The activation energy of the reaction is 12,000 Jmol-. The flow reactor has the following residence time distribution (RTD): E(t)=0 for t2 min (a) Calculate the conversion of A. [13 marks] (b) Calculate the mean residence time. 17 marks] (c) Compare the conversion of A in part (a) with the conversion i the reaction is carried out in a plug flow reactor (PFR) and a continuous flow stirred tank reactor (CSTR) at a residence time the same as the mean residence time in the flow reactor (calculated in part (b)).
