Predict the sign of entropy change for each of the following changes of state.

Options

A. `Hg(l) rarr Hg(g)`
B. `AgNO_(3)(s) rarr AgNO_(3)(aq)`
C. `I_(2)(g) rarr I_(2)(s)`
D. `C("graphite") rarr C("diamond")`

Explanation

To predict the sign of entropy change for each of the given changes of state, we will analyze each situation based on the degree of randomness or disorder of the system. Here's a step-by-step solution:

### Step 1: Understanding Entropy
Entropy (S) is a measure of the disorder or randomness of a system. The greater the disorder, the higher the entropy. Generally, the order of entropy from lowest to highest is:
- Solid < Liquid < Gas

### Step 2: Analyzing Each Change of State
