  1. Question 1

    Q1. In an energy profile diagram, what does the vertical distance between the energy of reactants and the energy of products represent?

    • A) Activation energy of the forward reaction
    • B) Activation energy of the reverse reaction
    • C) Enthalpy of the reaction
    • D) Potential energy of the activated complex

    Answer: Enthalpy of the reaction

    Explanation: Enthalpy change is the difference between product and reactant energy. Option A is activation energy, which is distinct from net heat.
