    Answer:

    Ea = 210.5kJ/mole

    Explanation:

    When the reaction:

    O3 + NO → O2 + NO2

    Occurs, requires 10.7kJ/mole and releases -199.8kJ/mole.

    For the forward reaction:

    O2 + NO2 → O3 + NO

    The Ea is the sum of Ea of the forward reaction and – ΔH, that is:

    Ea = Ea – (-ΔH)

    Ea = 10.7kJ/mol – (-199.8kJ/mol)

    Ea = 210.5kJ/mole
