The entropy change in the fusion of one mole of a solid melting at  27°C (Latent heat of fusion,  2930 J mol−1) is:

                               

  1. 9.77 J K−1mol−1
  2. 10.73 J K−1mol−1
  3. 108.5 J K−1mol−1
  4. 2930 J K−1mol−1

Solution

ΔS=Latent  heat  of  fusionMelting  point=ΔHfT=2930  J mol−1300K=9.77 J K−1mol−1
