4. Simple reactor sizing. The reaction A →B is to be carried out isothermally in a continuous- flow reactor. The entering volumetric flow rate vo is 10 L/h. Calculate both the CSTR and PFR reactor volumes (in L) necessary to consume 99% of A (i.e., CA = = 0.01 CAO) when the entering molar flow rate is 5 mol/h, assuming the reaction rate -r is: (a) -rA = k with k = 0.005 mol/h L - CSTR - PFR (b) -ra = k CA with k = 0.0001 s-1 - CSTR - PFR (c) -rA = K CA² with k = 300 L/mol h - CSTR - PFR Note: Since FA= CA V then = = CAO FAO/VO [5 mol/h]/[ 10 L/h]= 0.5 mol/L FA= CA VO Also, for a constant volumetric flow rate v = V0, SO
