Nitrogen combines with hydrogen to form ammonia. $\text{N}_2(g) + 3\text{H}_2(g) \rightleftharpoons 2\text{NH}_3(g)$. An initial mixture containing 2.00 mol of nitrogen, 6.00 mol of hydrogen, and 2.40 mol of ammonia is left to attain equilibrium in a sealed vessel with volume $1\,\text{dm}^3$ under specified conditions. It was determined that 2.32 mol of nitrogen remained in the equilibrium mixture. What is the value of $K_c$ under these conditions?
- A$\dfrac{(1.76)^2}{(2.32)(6.96)^3}$
- B$\dfrac{(1.76)^2}{(2.32)(6.32)^3}$
- C$\dfrac{(2.08)^2}{(2.32)(6.32)^3}$
- D$\dfrac{(2.40)^2}{(2.32)(6.00)^3}$
