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) ?

The standard molar entropy of H_(2) O_((l)) is 70 "JK"^(-1) "mol"^(-1)

1.	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) ?
Answer» Solution : 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)`.
