Which statement best describes the relationship between activation energy and rate of reaction?
A. Increasing the activation energy can increase the rate of a reaction.
B. Reducing the activation energy can increase the rate of a reaction.
C. Increasing the reaction energy does not alter the rate of reaction.
D. Reducing the activation energy can decrease the rate of a reaction.

Reducing the activation energy increases the rate of a reaction by allowing more molecules to exceed the energy barrier necessary for the reaction to occur. Enzymes are one example of how activation energy can be lowered to facilitate faster reactions. Conversely, increasing activation energy will slow down the reaction by making it harder for molecules to collide successfully.

Reducing the activation energy increases the reaction rate by allowing more molecules to achieve the required energy for the reaction. Conversely, increasing activation energy slows the reaction down. Enzymes are examples of catalysts that lower activation energy and speed up reactions. ;
