NEET Chemistry Activation Energy MCQ Question
Consider a potential energy vs reaction coordinate diagram for the formation of hydrogen iodide (HI) from hydrogen (H2) and iodine (I2). Which part of the diagram represents the activation energy for the reaction?
The peak of the curve
The initial potential energy of reactants
The difference in potential energy between reactants and products
The potential energy of the products
Correct Answer
Detailed Explanation
The activation energy is represented by the energy barrier that must be overcome for a reaction to proceed, which corresponds to the peak of the potential energy curve.
