The standard molar entropy of H(2) O((l)...

The standard molar entropy of `H_(2) O_((l))` is 70 `"JK"^(-1) "mol"^(-1)`. Will the standard molar entropy of `H_(2) O_((s))` be more, or less than 70 `"JK"^(-1) "mol"^(-1)` ?

Text Solution

Verified by Experts

The standard molar entropy of `H_(2) O_((l))` is 70 `JK^(-1) "mol"^(-1)`.
The solid form of `H_(2) O` is ice. In ice, molecules of `H_(2)O` are less random than in liquid water.
Thus, molar entropy of `H_(2) O_((s)) lt` molar entropy of `H_(2) O_((l))`. The standard molar entropy of `H_(2) O_((s))` is less than `70 "JK"^(-1) "mol"^(-1)`.
