Answer #1

In order to understand this let us write the performance equation or the design equation of a CSTR

where V is the volume of the reactor

Fao is molar flow rate

Tau is the residence time

Cao is the initial concentration

Xa is the conversion of reactant, say reactant A

-ra = rate equation of the reaction

now from the design equation we can see that the residence time (Tau) is directly proportional to the volume

Hence since both are proportional

error in residence time will also be proportional

Hence the expected error in the reactor volume will also be 0.2 hr
