This Demonstration examines a two-stage continuous-flow stirred tank reactor (CSTR). Conversion to an intermediate product of consecutive chemical reactions can be maximized in a combination of two CSTRs operating in series.

Consider the consecutive first-order chemical reaction with , , and representing reactants, products, and waste, involving the equations and . Here , , and are the rate constants, Arrhenius constants, and activation energies of the products and reactants, and is the temperature.

The equations describing the steady state condition of the CSTR are: and , where and are the concentrations, is the flow rate, and is the reactor volume for reactors and 2, with initial conditions and .
