A liquid-phase reaction takes place in two CSTR reactors operating at steady state in parallel and at the same temperature. One reactor is twice the size of the other. The total feed stream is split proportional to their volumes between the two reactors to achieve a desired removal efficiency. The smaller reactor needs to be taken out of service for repair. If the total feed rate stays the same, how much does the removal efficiency change (in percentage)? Assume that the reaction is first order and take the reaction rate as the reciprocal of the residence time of the smaller reactor.
