    Energy of activation of forward reaction for an endothermic process is 90 kJ. If enthalpy change for the reaction is 50 kJ then activation energy for backward reaction will be

    A)  40kJ  

    B)  140kJ

    C)  90 kJ  

    D)  50 kJ

    Correct Answer: A

    Solution :

     Given, \[{{E}_{f}}=90\,kJ\] \[{{E}_{b}}=?\] \[\Delta H=50\,kJ\] \[\Delta H={{E}_{f}}-{{E}_{b}}\] \[50=90-{{E}_{b}}\] \[{{E}_{b}}=(90-50)kJ\] \[{{E}_{b}}=40\,kJ\]
