The standard molar entropy of H2O (l )
Question:

The standard molar entropy of H2O (l ) is 70 J K–1 mol–1. Will the standard molar entropy of H2O(s) be more, or less than 70 J K–1 mol–1?

Solution:

The entropy of H2O(s) <entropy of H2O (l ). The standard molar entropy of H2O(s) will also be less than 70 J K–1 mol–1.
