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 with a volume of $1\,\text{dm}^3$ contains a mixture of $2.00$ mol of nitrogen, $6.00$ mol of hydrogen and $2.40$ mol of ammonia, and this mixture is left until equilibrium is reached. The equilibrium mixture is then found to contain $2.32$ mol of nitrogen. Which expression could be used to determine the value of $K_c$?
- A$\frac{(1.76)^2}{(2.32)(6.96)^3}$
- B$\frac{(1.76)^2}{(2.32)(6.32)^3}$
- C$\frac{(2.08)^2}{(2.32)(6.32)^3}$
- D$\frac{(2.40)^2}{(2.32)(6.00)^3}$
