The reaction a b is to be carried out isothermally in a continuous-flow reactor. the entering volumetric flow rate v0 is 10 dm3/h. (note: . for a constant volumetric flow rate , then . also, .) calculate both the cstr and pfr reactor volumes necessary to consume 99% of a (i. e., ca = 0.01ca0 ) when the entering molar flow rate is 5 mol/h, assuming the reaction rate –ra is
