Which outcome results when thermal runaway causes Arrhenius rate constant increase in a chemical microreactor?

💡 Explanation

When thermal runaway increases the Arrhenius rate constant, the elevated temperature exponentially increases reaction rate because temperature is directly related to the rate constant, causing enhanced heat production from the exothermic reaction. Therefore uncontrolled reaction ensues via autocatalysis, rather than viscosity increase, shift or reagent depletion which are affected by different parameters.
