Question

Explain thoroughly and answer

At a certain temperature, the reaction below has an equilibrium constant of 42. Which of the following is correct if 2.0 moles of hydrogen, 3.0 moles of oxygen, and 6.0 moles of water are placed in a 12.0 L container and allowed to reach equilibrium at this temperature?

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

- \( \bigcirc \) Q = 0.33 and the system reaches equilibrium by increasing the amount of \( \text{H}_2\text{O} \).
- \( \bigcirc \) Q = 3.0 and the system reaches equilibrium by increasing the amount of \( \text{H}_2\text{O} \).
- \( \bigcirc \) Q = 3.0 and the system reaches equilibrium by decreasing the amount of \( \text{H}_2\text{O} \).
- \( \bigcirc \) Q = 36 and the system reaches equilibrium by decreasing the amount of \( \text{H}_2\text{O} \).
- \( \bigcirc \) Q = 36 and the system reaches equilibrium by increasing the amount of \( \text{H}_2\text{O} \).
