A chemical reaction occurs when the energy of the reacting molecules is __________________ the activation energy of the reaction?
Correct answer: D. Equal to or more than
- A. Less than
- B. Equal to
- C. More than
- D. Equal to or more than
Explanation
Molecules must have energy at least equal to the activation energy to cross the reaction-energy barrier, so the condition is equal to or more than the activation energy.
