Question
**Educational Website Content: Predicting Reaction Entropy**

For each chemical reaction listed in the first column of the table below, predict the sign (positive or negative) of the reaction entropy (ΔS_rxn). If it's not possible to decide with the information given, check the "not enough information" option in the last column.

**Note for advanced students**: Assume the temperature remains constant. Assume all gases and solutions are ideal.

**Table:**

| Reaction | Sign of Reaction Entropy |
|----------|--------------------------|
| \( \text{N}_2(g) + 3\text{H}_2(g) \rightarrow 2\text{NH}_3(g) \) | ⬤ \( \Delta S_{rxn} < 0 \) <br> ○ \( \Delta S_{rxn} > 0 \) <br> ○ not enough information. |
| \( 2\text{SO}_3(g) \rightarrow 2\text{SO}_2(g) + \text{O}_2(g) \) | ○ \( \Delta S_{rxn} < 0 \) <br> ○ \( \Delta S_{rxn} > 0 \) <br> ⬤ not enough information. |
| \( 2\text{CH}_3\text{OH}(g) + 3\text{O}_2(g) \rightarrow 2\text{CO}_2(g) + 4\text{H}_2\text{O}(g) \) | ○ \( \Delta S_{rxn} < 0 \) <br> ○ \( \Delta S_{rxn} > 0 \) <br> ⬤ not enough information. |

**Explanation:**

1. **First Reaction (\( \text{N}_2(g) + 3\text{H}_2(g) \rightarrow 2\text{NH}_3(g) \)):**
   - Entropy decreases because the number of gas molecules decreases (4 to 2); thus, \( \Delta S_{rxn} < 0 \) is the correct choice.

2. **Second Reaction (\( 2\text{SO}_3(g) \rightarrow 2\text{SO}_2(g) + \text{O}_2(g) \)):**
   - The information is insufficient to determine the entropy change directly
