At a certain temperature, 0.10 mole of $\mathrm{H}_{2}$ and 0.10 mole of $\mathrm{I}_{2}$ were placed in a 1.0 L flask. The purple colour of iodine vapor was used to monitor the reaction. After the equilibrium was established. It was found that the concentration of $\mathrm{I}_{2}$ decreased to $0.02 \mathrm{~mole} / \mathrm{L}$ . Calculate the value of $\mathrm{K}_{\mathrm{c}}$ for the reaction at the given temperature.
