Interpretation: The comparison between the molar heat of fusion and the molar heat of solidification is to be drawn.
Concept introduction:
The molar enthalpy of fusion
The molar enthalpy of solidification
Answer to Problem 28LC
The molar enthalpy of solidification is exactly the same as the molar enthalpy of fusion.
Explanation of Solution
As fusion and solidification are opposite processes, heat absorbed in one is the same in magnitude as the heat released in the other. As in fusion, heat is absorbed, the molar enthalpy of fusion is positive, and in solidification, heat is released, and the molar enthalpy of fusion is negative with the same numerical value.
