Question

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 only increases the number of reacting particles, changing the reaction rate but not activation energy. Changing the potential energy of products or reactants doesn't directly reduce activation energy. Raising the temperature increases the kinetic energy of particles and reaction rate, but not by reducing activation energy.

Answer:

A. adding a catalyst to the reaction
