In a continuous flow reactor, the following reaction M- N is carried out isothermally. The exit concentration of reactant is 15 % of the initial concentration. The input flow rate of the reactant is given as 0.3 mol/min. The reaction rate law is given by: -M = kCM with the rate constant k = 0.002 s. The entering volumetric flow rate is 0.1 m /min .

Question
In a continuous flow reactor, the following reaction M-N is carried out isothermally. The exit
concentration of reactant is 15 % of the initial concentration. The input flow rate of the reactant is
given as 0.3 mol/min. The reaction rate law is given by: -M = kCM with
k = 0.002 s. The entering volumetric flow rate is 0.1 m /min.
the rate constant
(a) Calculate the volume of CSTR.
(b) Calculate the volume of PFR.
(c) Explain and prove the condition at which the volumes of CSTR and PFR are equal.
Given data:
Gas constant (R) = 1.987 cal K-1.mole- = 8.21 x 102 L. atm. K1 mole = 8.3145 J K1. mole
