Answer: Graph 3
Explanation:
Activation energy is the level of energy required by a chemical reaction for the reaction to proceed.
A higher Activation energy will translate to a lower reaction rate because less molecules will be able to achieve this required energy needed for them to react. A lower activation energy however will enable a faster reaction time because more molecules will achieve the required energy.
Higher Activation energy = Lower Reaction rate
Lower Activation energy = Higher reaction rate
This is what Graph 3 shows so it is correct.
