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

Options

A. `DeltaH = Delta G`
B. `Delta H lt T Delta S`
C. `Delta H gt T Delta S`
D. `Delta H= T Delta S`

Answer

B

Explanation

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`
