For the reaction H_(2)O_((s)) hArr H_(2)O_((l)) at ""^(@)C and normal pressure

Answer»

`DELTAH = Delta G`
`Delta H lt T Delta S`
`Delta H GT T Delta S`
`Delta H= T Delta S`

Solution :For the reaction to be spontaneous, `Delta G = Delta H - T Delta S` should be negative. As in the given reaction solid phase changes to the liquid phase entropy increases for `Delta G` MUST be negative.
`Delta H lt T Delta S`
