The compromise to maximize both selec vity and throughput can be found through the use of cascading CSTR reactors. In the context of an electrochemical CSTR, the overall conversion of the reac on reached in each individual stage of the CSTR would be dependent on current applied, as well as the average residence me (t) in each stage. In a CSTR, residence me is dependent on the volume of solu on inside the reactor (V) and the flow rate (Q); and thus, is a design element for CSTR (Eq. 2).
