Nitrogen combines with hydrogen to form ammonia. $\text{N}_2(g) + 3\text{H}_2(g) \rightleftharpoons 2\text{NH}_3(g)$ A sealed vessel containing a mixture of $1.00\,\text{mol}$ of nitrogen, $3.00\,\text{mol}$ of hydrogen and $1.98\,\text{mol}$ of ammonia is left until equilibrium is reached under specified conditions. It was determined that $1.64\,\text{mol}$ of nitrogen was present in the equilibrium mixture. What is the value of $K_c$ for these conditions?
- A$\dfrac{(0.70)^2}{(1.64)(4.92)^3}$
- B$\dfrac{(1.34)^2}{(1.64)(3.64)^3}$
- C$\dfrac{(1.64)(4.92)^3}{(0.70)^2}$
- D$\dfrac{(1.64)(3.64)^3}{(1.34)^2}$
