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.
Answer (2)
The relationship between activation energy and reaction rate is clear: reducing activation energy increases the rate of reaction. When activation energy is lowered, more molecules can react. Therefore, the correct answer is that reducing the activation energy can increase the rate of a reaction.
;
Reducing the activation energy increases the rate of a reaction by allowing more molecules to overcome the energy barrier. Increasing activation energy would slow the reaction rate. Understanding this relationship is key to studying chemical kinetics. ;
