Which of the following lowers the activation energy of a reaction?

Question

Quizplus · Accepted Answer

Adding a catalyst lowers the activation energy of a reaction by providing an alternative reaction pathway with a lower activation energy barrier. This allows the reaction to proceed at a faster rate and with less energy input. Adding reactants or removing products can increase the rate of a reaction, but it does not lower the activation energy. Lowering the temperature decreases the rate of the reaction by decreasing the amount of energy available for reaction. Raising the temperature can increase the rate of the reaction, but it also increases the activation energy required for the reaction to occur.
