Consider the equilibrium: \(\text{N}_2(\text{g}) + 3\text{H}_2(\text{g}) \rightleftharpoons 2\text{NH}_3(\text{g})\)
What is the equilibrium constant expression, \(K_c\)?

• A

  \( \frac{[\text{NH}_3]}{[\text{N}_2][\text{H}_2]} \)

• B

  \( \frac{[\text{NH}_3]^2}{[\text{N}_2][\text{H}_2]^3} \)

• C

  \( \frac{[\text{N}_2][\text{H}_2]^3}{[\text{NH}_3]^2} \)

• D

  \( \frac{[\text{N}_2][\text{H}_2]}{[\text{NH}_3]} \)
