![3. The reaction
A > B
is to be carried out isothermally in a continuous-flow reactor. The entering
volumetric flow rate vo is 10 dm³/h. (Note: FA = CAv. For a constant volumetric
flow rate v = vo then FA = CAVO. Also, CAo = FAo/Vo = ([5 mol/h]/ [10 dm³/h]) 0.5
mol/dm3.)
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
(a) -ra = k with k = 0.05 mol/h'dm3
(b) -rA = kCA with k = 0.0001s
(c) –rA = with k = 300 dm³/mol·h

99.9% of species A in a 1000 dm³ constant-volume batch reactor with Cao
0.5 mol/dm³.
