    The favourable conditions for a spontaneous reaction are

    A) \[T\Delta S>\Delta H,\Delta H=+ve,\text{ }\Delta S=+ve\]

    B) \[T\Delta S>\Delta H,\text{ }\Delta H=+ve,\text{ }\Delta S=-ve\]

    C) \[T\Delta S=\Delta H,\text{ }\Delta H=-ve,\text{ }\Delta S=-ve\]

    D) \[T\Delta S=\Delta H,\text{ }\Delta H=+ve,\,\,\Delta S=+ve\]

    Correct Answer: A

    Solution :

    [a] \[\Delta G=\Delta H-T\Delta S,\text{ }\Delta H\text{ }is+ve,\] \[\Delta S\] is \[+ve;T\Delta S>\Delta H\] for spontaneous process. It will make \[\Delta G,\,\,-ve\]
