Question
- A. They lose energy and stop moving
- B. They gain energy and react
- C. They remain at the same energy level
- D. They convert energy into mass
Answer
They gain energy and react
Explanation
When particles collide with sufficient energy, they gain energy which allows them to overcome the activation energy barrier and react.
Common mistake
Confusing Activation Energy
Students often confuse activation energy with the overall energy change of a reaction.
Remember that activation energy is the minimum energy required for particles to react, while overall energy change refers to the difference in energy between reactants and products.
