Analytical expressions are derived for the time and magnitude of failure of an isothermal CSTR with substrate‐inhibited kinetics, caused by slow catalyst deactivation under three types of parallel and series mechanisms. Reactors operating at high space velocity are found to be most susceptible to early failure and poisoning by product is more dangerous than by reactant. The magnitude of the jump across steady states depends solely on the Langmuir‐Hinshelwood kinetic parameters and a detailed analysis of reactor behavior during the jump itself is given.
