solve all from a to d

is to be carried out isothermally in a continuous-flow reactor. 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 5mol/h, assuming the reaction rate rA is: (a) rA=k with k=0.05hdm3mol (Ans.: V=99dm3 ) (b) rA=kCA with k=0.0001s1 (c) rA=kCA2 with k=3molhdm3 (Ans.: VCSTR=66,000dm3 ) The entering volumetric flow rate is 10dm3/h. (Note: FA=CAv. For a constant volumetric flow rate v=v0, then FA=CAv0. Also, CA0=FA0v0= [5mol/h][10dm3/h]=0.5mol/dm3.) (d) Repeat (a), (b), and (c) to calculate the time necessary to consume 99.9% of species A in a 1000dm3 constant volume batch reactor with CA0=0.5 mol/dm3
