NEET Chemistry Activation Energy MCQ Question
Consider a potential energy vs reaction coordinate diagram that shows the formation of an unstable intermediate during the reaction between hydrogen and iodine to form hydrogen iodide. What is the role of the peak in this diagram?
Represents the activation energy barrier.
Indicates the final energy of the reaction.
Shows the energy of products only.
Marks the starting energy of reactants.
Correct Answer
Detailed Explanation
The peak in the potential energy vs reaction coordinate diagram represents the activation energy barrier, which is the minimum energy required for the formation of the unstable intermediate, as per the NCERT context.
