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

Question

Quizplus · Accepted Answer

Adding a catalyst lowers the activation energy for a reaction by providing an alternate reaction pathway with lower activation energy. This allows the reaction to proceed faster and with less energy input. Increasing the concentrations of reactants and raising the temperature of the reaction can increase the rate of the reaction, but they do not lower the activation energy. Removing products as the reaction proceeds and increasing the pressure do not affect the activation energy.
