Of the following, will lower the activation energy for a reaction.

Question

Quizplus · Accepted Answer

Adding a catalyst for the reaction will lower the activation energy for the reaction by providing an alternative pathway for the reaction with a lower activation energy barrier. Raising the temperature (A) and increasing the concentration of reactants (B) can increase the reaction rate, but they do not lower the activation energy. Removing products (D) as the reaction proceeds may also increase the reaction rate, but it does not affect the activation energy. Increasing the pressure (E) may affect the equilibrium constant of the reaction, but it does not lower the activation energy.
