You have an elmentary, liquid phase, irreversible reaction. A + B goes to C. You have two different reactor choices. A 300 m3 PFR and a 500 m3 CSTR. You want to do the reaction at 400 K. If at that condition k=0.1 m3/molmin, energy of activiation is 100,000 J/molK, the inlet concentrations of both components are 2 mol/m3, and the flow rate of the liquid stream 20 m3/min; which reactor should you chose?
