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)`.
