    If\[\Delta H\]and\[\Delta S\]are positive for a reaction, the reaction will be spontaneous only when

    A)  \[T\Delta S=\Delta H\]

    B) \[T\Delta S>\Delta H\]

    C)  \[T\Delta S<\Delta H\]

    D) \[T\Delta S\]is negative

    Correct Answer: B

    Solution :

     \[\Delta G=\Delta H-T\Delta S\]for spontaneity, \[\Delta {{G}^{o}}<0\]and this occurs when \[T\Delta S>\Delta H\]
