[The reactionA->Bis to be carried out isothermally in a continuous-flow reactor. The entering volumetric flow rate v0 is 10 dm^3/h. (Note: F _A =C _A * v. For a constant volumetric flow rate v=v0, then . Also, F _A =C _A *v0. Also, C _A0 =F _A0 /V0 ([5mol/h]/[10 dm^3/h]=0.5 mol/dm^3.)
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 -r _A is
(a) -r _A = k with k = 0.05 mol/(h*dm^3)
(b) -r _A = kC _A with k = 0.0001 s ^-1 ?
(c) -r _A = with k = 300 dm^3/(mol*h)
(d) Repeat (a), (b), and/or (c) to calculate the time necessary to consume 99.9% of species A in a 1000 dm^3 constant-volume batch reactor with C _A0 = 0.5 mol/dm^3.
