Complete the derivation of performance equations for a continuously stirred tank reactor

$($CSTR$)$ assuming zero$-$order reaction kinetics and assuming second$-$order reaction kinetics Start from a pollutant mass balance. Derive the general

performance equation for a CSTR$.$ Use the general performance equation to derive the

performance equations for zero$-$order and second$-$order CSTRs $($two performance

equations for each reaction order$).$
