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?​

Answer 1

Answer:

The standard molar entropy of H2O (1) is 70 J K-1 mol-1. The solid form of H2O is ice. In ice, molecules of H2O are less random than in liquid water. Thus, molar entropy of H2O (s) < molar entropy of H2O (1). The standard molar entropy of H2O (s) is less than 70 J K 1 mol-1.
