Question
- A. The total number of particles
- B. The number of particles that can react
- C. The energy of the products
- D. The energy of the reactants
Answer
The number of particles that can react
Explanation
The area beyond the activation energy on a Maxwell-Boltzmann distribution curve represents the fraction of particles that have sufficient energy to overcome the activation energy barrier and thus can react.
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 a barrier that must be overcome for reactants to convert into products.
