    The energy of activations for forward and backward change for an endothermic reaction; X \[\to \] Y are \[{{E}_{F}}\] and \[{{E}_{b}}\] respectively. Which is correct?

    A)  \[{{E}_{b}}<{{E}_{F}}\]

    B)  \[{{E}_{b}}>{{E}_{F}}\]

    C)  \[{{E}_{b}}={{E}_{F}}\]

    D) No relation between them

    Correct Answer: A

    Solution :

    [a] \[\Delta H={{E}_{f}}-{{E}_{b}}\] \[\Delta H=+ve\] \[\therefore {{E}_{f}}>{{E}_{b}}\]
