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 activation energy increases the rate of a reaction because more molecules can overcome the energy barrier. Conversely, increasing activation energy decreases the reaction rate. Enzymes are a common example of reducing activation energy to speed up reactions. ;
