  • question_answer
    For spontaneity of a cell, which is correct

    A) \[\Delta G=0,\,\Delta E=0\]

    B) \[\Delta G=-ve,\,\Delta E=0\]

    C)  \[\Delta G=+ve,\,\Delta E=+ve\]

    D) \[\Delta G=-ve,\,\Delta E=+ve\]

    Correct Answer: D

    Solution :

    [d] \[\Delta G=\Delta H-T\Delta S\];  \[\Delta G=\Delta E+P\Delta V-T\Delta S\]
    For spontaneity \[(\Delta G=-ve)\]
                \[\because \]  \[\Delta G=-ve\], \[\Delta E=+ve\]
