Type: MCQ-diagram based-Easy-Class 12
Consider a potential energy diagram where the y-axis represents potential energy and the x-axis represents the reaction coordinate. Which point on the diagram corresponds to the activation energy for the formation of HI from H2 and I2?
A
The peak of the energy barrier.
B
The initial energy level of the reactants.
C
The final energy level of the products.
D
The midpoint between reactants and products.
Correct Answer
Option A
Detailed Explanation
The activation energy is represented by the peak of the energy barrier in a potential energy diagram, as it is the energy required to reach the transition state from the reactants.
