    For the exothermic reaction \[A+B\to C+D,\text{ }\Delta H\]is the heat of reaction and \[{{E}_{a}}\]is the energy of activation. The energy of activation for the formation of A + B will be

    A) \[{{E}_{a}}\]                           

    B) \[\Delta H\]

    C) \[{{E}_{a}}+\Delta H\]             

    D) \[\Delta H-{{E}_{a}}\]

    Correct Answer: C

    Solution :

    [c] For the exothermic reaction the energy of products is always less than the reactants. If \[{{E}_{\text{a}}}\] is the energy of activation for the forward reaction, the energy of activation for backward reaction is \[{{E}_{a}}+\Delta H\]
