Transcribed Image Text:The reaction
AB
Is to be carried out isothermally in Continous-flow reactor (can be CSTR PFR or PBR). The entering
volumetric flow rate vo is 10 dm³/h. Note that FA = CA. V. For a constant volumetric flow rate v= vo, then
FA = CA. Vo.
Also CAo = FAo/ Vo = (5 mol/h)/(10 dm³/h) = 0.5 mol/dm3.
%3D
Calculate both CSTR and PFR reactor volumes necessary to consume 99% of A (CA = 0.01CA0) when the
entering molar flow rate (FAo) is 5 mol/h, assuming the reaction rate is -rA is:
a) -rA = k
with k= 0.05 mol/h.dm3
b) -rA = k. CA
with k= 0.0001 s1
c) -rA = k. CA?
with k= 0.03 dm³/mol.h
d) Repeat a), b), and c) to calculate the time necessary to consume 99.9% of species A in a 1000 dm3
constant volume batch reactor with CAo = 0.5 mol/dm³.
