AB is to be carried out isothermally in a flow reactor. Calculate both the CSTR and PFR reactor volumes necessary to consume 80% of A(i.e.,CA=0.2CA0 ) when the entering feed is pure A at a flow rate of 20mol/h, assuming the reaction rate rA is: (a) rA=k with k=0.045mol/hdm3 (b) rA=kCA with k=0.0001s1 (c) rA=kCA2 with k=3dm3/molh The entering volumetric flow rate, v0, is 15dm3/h. [Note: FA=CAv. For a constant volumetric flow rate v=v0, then FA=CAv0. Also, CA0=FA0/v0]
