Question

32 select the correct answer. which action would reduce the activation energy of a chemical reaction? a. adding a catalyst to the reaction b. adding more reactants to the reaction vessel c. lowering the potential energy of the products d. lowering the potential energy of the reactants e. raising the temperature of the reaction

Explanation:

A catalyst works by providing an alternative reaction pathway with a lower activation - energy barrier. Adding more reactants affects the reaction rate through collision theory but not the activation energy. Changing the potential energy of products or reactants does not directly lower the activation energy. Raising the temperature increases the kinetic energy of reactant molecules but does not change the activation energy itself.

Answer:

A. adding a catalyst to the reaction
