Ammonia is produced from nitrogen and hydrogen by the Haber process. $\text{N}_2(g) + 3\text{H}_2(g) \rightleftharpoons 2\text{NH}_3(g)$ What is the expression for $K_c$ for this equilibrium?
- A$\dfrac{2[\text{NH}_3(g)]}{[\text{N}_2(g)] + 3[\text{H}_2(g)]}$
- B$\dfrac{2[\text{NH}_3(g)]}{[\text{N}_2(g)] \times 3[\text{H}_2(g)]}$
- C$\dfrac{[\text{NH}_3(g)]^2}{[\text{N}_2(g)] + [\text{H}_2(g)]^3}$
- D$\dfrac{[\text{NH}_3(g)]^2}{[\text{N}_2(g)] \times [\text{H}_2(g)]^3}$
