Answer to Question #337487 in Chemical Engineering for Vhadau

Question

A CSTR is fed with a solution of reactant A of concentration 10 kmol/m3

at a flow rate of 0.02

m3

/s. The product mixture from the first CSTR is fed into a second CSTR of twice the volume

of the first CSTR. The two CSTRs in series are required to achieve an overall conversion of

80%.

The reaction A → B is first order with respect to A (-rA = kCA) with a reaction rate constant of

0.2 s-1

. Assuming constant liquid density, what is the volume of the first CSTR?
