B. The elementary irreversible organic liquid phase reaction FA+B+C + 2D C is carried out in a flow reactor with a constant volumetric flowrate of 3.5dm3/s. The initial entering concentration of A and B are 3.25 and 7.3 mol/dm3, respectively. The specific rate constant is 0.045 (dm3)52/molt/2.s. at 180C with the activation energy of 110,000 J/mol. Taking the species A as the limiting reactant. (a) Calculate the rate of reaction when the conversion of A is 60% at 140 C and 250 C. (b) If plug flow reactor (PFR) is used for this reaction, determine the PFR volume for 80% conversion at 140 C
