Question: 218
3. Which of the following is represented by a localized minimum in a reaction coordinate diagram?
- A. Transition state
- B. Product
- C. Activated complex
- D. Intermediate
Correct Answer: D
Explanation:
D It should be noted that choices A and C are the same and should therefore be eliminated. Additionally, transition states are localized maximums, not minimums. Choice B is incorrect because the product for a spontaneous reaction is the absolute minimum and not a localized minimum. Intermediates are formed and then used. They have a certain lifespan represented by a local minimum on the reaction coordinate diagram.
