The reaction BC is carried out in a flow reactor under isothermal conditions. The inlet volumetric flow rate is 10L/h and the inlet molar flow rate of B is 4mol/h. The volumetric flow rate changes little (vv0). Calculate the CSTR and PFR reactor volumes needed to consume 90% of B, assuming the reaction rate, r is: (a) r=k, with k=0.05mol/hL (b) r=kCCB3, with k=1104/s +43 (d) r=k, with k=0.05mol/hL (e) r=kCBE2, with k=3L/molh
