← ScienceWhich outcome is observed when an unmixed batch reactor runs an exothermic reaction without adequate cooling?
A)Exponential reaction rate increase✓
B)Equilibrium shift to reactants
C)Catalyst poisoning from side products
D)Lower activation energy due to heat
💡 Explanation
When an exothermic reaction lacks adequate cooling, the temperature rises, causing the reaction rate constant to exponentially increase because the rate is described by the Arrhenius equation, leading to accelerated heat production. Therefore the reaction rate increases exponentially, rather than shifting equilibrium or catalyst poisoning, which require other conditions.
