Which consequence results when a chemical reactor’s cooling system cannot maintain isothermal operation during an exothermic reaction?

💡 Explanation

Thermal runaway occurs because an increase in temperature leads to an increase in the rate constant, accelerating the reaction via the Arrhenius equation; therefore the reaction accelerates to uncontrollable levels and temperatures, rather than equilibrium limits changing or the catalyst deactivating.
