What is the entropy change (in `JK^(-1)mol^(-1)`) when one mole of ice is converted into water at `0^(@)C`?
(The enthalpy change for the conversion of ice to liquid water is `6.0KJmol^(-1)` at `0^(@)C`)

A

20.13

B

2.013

C

2.198

D

21.98

Text Solution

Verified by Experts

The correct Answer is:
D
`H_(2)O(s)hArr H_(2)O(l)`
According to thermodynamics,
`Delta S_(fus) = (Delta H_(fus))/(T_(f))`
`= (600 J mol^(-1))/(273 K) = 21.98 J k^(-1) mol^(-1)`
