What happens to the rate of reaction when the temperature increases and particles gain kinetic energy?

• A. Rate decreases
• B. Rate increases due to more collisions
• C. Rate stays the same
• D. Rate decreases due to faster movement

Answer: (B)

Raising the temperature gives particles more kinetic energy and makes them move faster. This causes collisions to occur more often and increases the likelihood that a collision has enough energy to overcome the activation energy. As a result, more collisions lead to a successful reaction per unit time, so the rate of reaction increases.
