Question

At 0 oC, if the enthalpy of fusion of ice is 1365 kcal/mol. Then, the molar entropy change for melting of ice at 0 oC in kJ/mol is.


Solution

Change in entropy for a phase transformation is given as:
Stransformation=HtransformationT
 
putting all the values from question we get:

Sfusion=HfusionT

Sfusion=1365273

Sfusion=5 kcal/mol
as 1 cal=4.18 J

Sfusion=20.9 kJ/mol
