Maximizing an Intermediate Reactant in a Continuous Stirred-Tank Reactor
Maximizing an Intermediate Reactant in a Continuous Stirred-Tank Reactor
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
