  • question_answer
    Consider an endothermic reaction \[X\to Y\] with the activation energies \[{{E}_{b}}\] and \[{{E}_{f}}\] for the backward and forward reactions, respectively, in general             [AIEEE 2005]

    A)                 \[{{E}_{b}}<{{E}_{f}}\]

    B)                 \[{{E}_{b}}>{{E}_{f}}\]

    C)                 \[{{E}_{b}}={{E}_{f}}\]

    D)                 There is no definite relation between \[{{E}_{b}}\] and \[{{E}_{f}}\]

    Correct Answer: A

    Solution :

               For endothermic reaction DH = +ve                                 Then from equation \[\Delta H={{E}_{{{a}_{F.R.}}}}-{{E}_{{{a}_{B.R.}}}};{{E}_{B.R.}}<{{E}_{F.R.}}\]
