Question 5 of 12

5. Question
Describe the relationship between an increase in temperature and the activation energy of molecules within a reaction.
- Increasing the temperature will result in a higher proportion of molecules having at least the activation energy and the ability to react
- Increasing the temperature will result in a lower proportion of molecules having at least the activation energy and the ability to react
- There is no relationship between an increase in temperature and the activation energy of molecules within a reaction
- The activation energy of molecules within a reaction will stay the same when the temperature of a reaction is increased
Correct

Incorrect
