  • question_answer
    The activation energy for a simple chemical reaction \[A\to B\] is \[{{E}_{a}}\] in forward direction. The activation energy for reverse reaction                                        [CBSE PMT 2003]

    A)                 Is always double of \[{{E}_{a}}\]

    B)                 Is negative of \[{{E}_{a}}\]

    C)                 Is always less than \[{{E}_{a}}\]

    D)                 Can be less than or more than \[{{E}_{a}}\]

    Correct Answer: D

    Solution :

                    In exothermic and endothermic reactions will be more and less than \[{{E}_{a}}\] respectively.
