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)` ?

Explanation

To determine whether the standard molar entropy of \( H_2O (s) \) (ice) is more or less than \( 70 \, J \, K^{-1} \, mol^{-1} \) (the standard molar entropy of \( H_2O (l) \) (liquid water)), we can follow these steps:

### Step 1: Understand the concept of entropy
Entropy is a measure of the randomness or disorder of a system. The greater the disorder, the higher the entropy.

### Step 2: Compare the states of matter
- In solids, the molecules are closely packed together and have limited movement, leading to lower randomness.
- In liquids, the molecules are less tightly packed than in solids and can move around more freely, resulting in higher randomness compared to solids.
