Question

which statement best describes the relationship between activation energy and rate of reaction?
increasing the activation energy can increase the rate of a reaction.
reducing the activation energy can increase the rate of a reaction.
increasing the reaction energy does not alter the rate of reaction.
reducing the activation energy can decrease the rate of a reaction.

Explanation:

Activation energy is the minimum energy required for a reaction to occur. Catalysts work by reducing activation energy, which in turn increases the rate of reaction as more reactant - molecules can overcome the energy barrier.

Answer:

Reducing the activation energy can increase the rate of a reaction.
