**Equilibrium Calculation for Chemical Reaction**

Consider the equilibrium system described by the chemical reaction below. At equilibrium, a 1.5 L reaction vessel contained a mixture of 5.0 × 10⁻² M SO₃, 3.5 × 10⁻³ M O₂, and 3.0 × 10⁻³ M SO₂ at 800 K. What are the values of \( K_c \) and \( K_p \) for the reaction at this temperature?

\[ 2 \text{ SO}_3(g) + \text{ O}_2(g) \rightleftharpoons 2 \text{ SO}_3(g) \]

---

**Task:**

Based on the given data, set up the expression for \( K_c \) and then evaluate it. Do not combine or simplify terms.

\[ K_c = \frac{{[SO_3]^2}}{{[SO_2]^2 \cdot [O_2]}} = \_\_\_\_ \]

**Choices for entering the answer in the expression:**

- \( [5.0 \times 10^{-2}] \)
- \( [3.5 \times 10^{-3}] \)
- \( [3.0 \times 10^{-3}] \)
- \( [2.5 \times 10^{-8}] \)
- \( [2.5 \times 10^{-1}] \)
- \( [2.3 \times 10^{-1}] \)
- \( [2.0 \times 10^{-9}] \)
- \( [1.3 \times 10^{3}] \)
- \( [3.3 \times 10^{-9}] \)
- \( [2.1 \times 10^{-4}] \)
- \( [4.8 \times 10^{9}] \)
