Which of the followingk is true for the process
`H_(2) O (s) = H_(2) O (l)`
at `0^(@)C` and 1 atm?

A

`Delta H = 0`

B

`Delta S = Delta H//T`

C

`Delta S = 0`

D

`Delta H = Delta U`

Text Solution

Verified by Experts

The correct Answer is:
B
At the transition temperature (that is, at the melting point or the boiling point), the system is at equilibrium `(Delta G = 0)`. So Eq. becomes
`= Delta H - T Delta S`
`Delta S = (Delta H)/(T)`
