![**Equilibrium System Analysis**
Consider the following chemical system at equilibrium:
\[ \Delta H^\circ = 198 \text{ kJ}, \quad K_c = 2.90 \times 10^{-2} \, \text{ at } 1.15 \times 10^3 \text{ K} \]
\[ 2\text{SO}_3(g) \rightleftharpoons 2\text{SO}_2(g) + \text{O}_2(g) \]
### Scenario: Volume Increase at Constant Temperature
When the volume of the equilibrium system is suddenly increased, analyze the following aspects:
1. **Value of \( K_c \):**
- A. Increases
- B. Decreases
- C. Remains the same
2. **Value of \( Q_c \) Relative to \( K_c \):**
- A. Greater than \( K_c \)
- B. Equal to \( K_c \)
- C. Less than \( K_c \)
3. **Reaction Direction:**
- A. Runs in the forward direction to reestablish equilibrium.
- B. Runs in the reverse direction to reestablish equilibrium.
- C. Remains the same, it is already at equilibrium.
4. **Number of Moles of \( \text{O}_2 \):**
- A. Increase
- B. Decrease
- C. Remain the same
