- B. The energy released during a reaction
- C. The energy needed to break bonds in reactants
- D. The energy required to form products
Answer
The minimum energy required for a reaction to occur
Explanation
Activation energy is defined as the minimum energy that reacting particles must possess for a reaction to occur. This energy is necessary to overcome the energy barrier for the 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.
