Question
- A. It decreases the number of effective collisions
- B. It increases the average energy of the particles
- C. It decreases the activation energy
- D. It has no effect on the reaction rate
Answer
It increases the average energy of the particles
Explanation
Increasing temperature raises the average kinetic energy of the particles, resulting in more particles having energy equal to or greater than the activation energy, thus increasing the rate of reaction.
Common mistake
Misunderstanding Activation Energy
Students often confuse activation energy with the overall energy change of a reaction, thinking it is the energy released or absorbed during the reaction.
Activation energy is the minimum energy required for a reaction to occur, not the energy change. To clarify, remember that activation energy is the energy barrier that must be overcome for reactants to convert into products.
