Question: 75
15. The potential energy diagram shown represents four different reactions.
Assuming identical conditions, which of the reactions displayed on the energy diagram proceeds the fastest?
- A. A
- B. B
- C. C
- D. D
Correct Answer: D
Explanation:
The faster a reaction can reach its activation energy, the faster it will proceed to completion. Because this question states that all conditions are equal, the reaction with the lowest activation energy will have the fastest rate. In the diagram, choice (D) has the lowest activation energy.
