Question

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

Explanation:

Activation energy is the minimum energy required for a reaction to occur. A lower activation - energy barrier means more reactant molecules have enough energy to react, thus increasing the reaction rate. So reducing the activation energy can increase the rate of a reaction.

Answer:

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