    The correct thermodynamic conditions for the spontaneous reaction at all temperatures is

    A)  \[\Delta H<0\]and \[\Delta S=0\]            

    B)  \[\Delta H>0\]and \[\Delta S<0\]

    C)   \[\Delta H<0\]and \[\Delta S>0\]

    D)   \[\Delta H<0\]and \[\Delta S<0\]

    Correct Answer: C

    Solution :

                                    \[\Delta G=\Delta H-T.\Delta S\] For, \[\Delta H<0\] and \[\Delta S>0,\Delta G=-ve\] (always) \[\therefore \] spontaneous at all temperatures.
