    For a reaction \[\Delta H=+29\,kJ\,mo{{l}^{-1}}\] \[\Delta S=-35\,kJ\,mo{{l}^{-1}}\] at what temperature the reaction will be spontaneous?

    A)  \[{{828.7}^{o}}C\]

    B)  \[828.7K\]

    C)  spontaneous at all temperature

    D)  not possible

    Correct Answer: D

    Solution :

    For spontaneous, \[\Delta H=\pm ve\] \[\Delta S=+\,\,ve\], But, in that reaction \[\Delta S\]is negative, so reaction is not possible.
