During an experiment, $2.00\ \text{mol}$ of hydrogen and $3.00\ \text{mol}$ of iodine were placed in a sealed container, then heated so that the reaction could reach equilibrium at a constant temperature. The container volume was kept at $1.00\ \text{dm}^3$. When equilibrium was reached, the mixture contained $2.40\ \text{mol}$ of iodine. $\text{H}_2\text{(g)} + \text{I}_2\text{(g)} \rightleftharpoons 2\text{HI(g)}$ Calculate the value of the equilibrium constant, $K_c$?
