This Demonstration determines the temperature that maximizes the exit concentration of the intermediate product in the reaction taking place in an isothermal continuous stirred-tank reactor; the concentration of species exiting the reactor is


, with



, and


where and are the reaction rates, and are the activation energies for the two reactions (with ), is the reactor temperature, and is the reactor residence time.
