  1. Question 1

    Q1. In the context of collision theory, what represents the configuration of atoms at the peak of the activation energy barrier?

    • A) A stable product of a fast step
    • B) A temporary high-energy state during a collision
    • C) A substance that can be isolated and stored
    • D) The reactant with the highest kinetic energy

    Answer: A temporary high-energy state during a collision

    Explanation: Activated complexes are high-energy, unstable species at the peak of the energy barrier. Option C is wrong because they cannot be isolated.
