**Equilibrium Reaction Analysis**

Given the following reaction, the equilibrium constant, and the initial concentrations; answer the four bullet questions.

**Reaction:**
\[ 2 \text{NO}_2 (g) \rightleftharpoons 2 \text{NO} (g) + \text{O}_2 (g) \]

**Equilibrium Constant:**
\[ K_c = 1.56 \times 10^{-10} \]

**Initial Concentrations:**

| Species | Initial Concentration (M) |
|---------|---------------------------|
| NO₂     | \( 5.62 \times 10^{-10} \) |
| NO      | \( 3.99 \times 10^{-16} \) |
| O₂      | \( 9.35 \times 10^{-3} \) |
