For the process : H_(2)O(l) (1 bar, 373 K) rarr H_(2)O(g) (1 bar, 373 K), the correct set of thermodynamic parameter is :

Answer»

`Delta G = 0, Delta S = + ve`
`Delta G = 0, Delta S = - ve`
`Delta G = + ve, Delta S = 0`
`Delta G = - ve, Delta S = + ve`

SOLUTION :This is a PHASE transformation and hence `Delta G = 0`. SINCE `H_(2)` is CHANGING to `H_(2)O (g)` at the same temperature and pressure. `Delta S = +ve`
