    A reaction occurs spontaneously if:

    A) \[T\Delta S=\Delta H\] and both \[\Delta H\]and \[\Delta S\]are positive

    B)  \[T\Delta S>\Delta H\]and both\[\Delta H\]and \[\Delta S\]are positive

    C)  \[T\Delta S>\Delta H\]and both \[\Delta H\]and\[\Delta S\]are positive

    D) \[T\Delta S>\Delta H\] and \[\Delta H\]is positive and\[\Delta S\]is negative

    Correct Answer: B

    Solution :

     For spontaneous reaction \[\Delta G=-ve.\] \[\Delta G=\Delta H-T\Delta S\] \[\Delta H=+ve,\Delta S=+ve\]and \[T\Delta S>\Delta H\]
