The standard molar entropy of `H_(2)O(l)` is 70 `JK^(-1)mol^-1`. Standard molar entropy of `H_(2)O(s)` is

A

more than 70 `JK^(-1)mol^(-1)`

B

less than 70 `JK^(-1)mol^(-1)`

C

equal to 70 `JK^(-1) mol^(-1)`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
Less than 70 `JK^(-1)mol^(-1)`, because ice is more ordered than `H_(2)O(l)`.
