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. A lower activation energy means more reactant molecules have sufficient energy to overcome the energy barrier and react. This leads to an increase in the rate of reaction. For example, catalysts work by reducing the activation energy of a reaction, thereby increasing the reaction rate.

Answer:

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