Chemistry - Chemical Equilibrium Question with Solution | TestHub

For the reaction$2\mathrm{H}\mathrm{I}\left(\mathrm{g}\right)\rightleftharpoons {\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{I}}_2\left(\mathrm{g}\right)$. The value of${\mathrm{K}}_{\mathrm{c}}$is 4. If 2 mol of${\mathrm{H}}_2$, 2 mol of${\mathrm{I}}_2$and 2 mol of HI are present in one litre container then moles of${\mathrm{I}}_2$present at equilibrium is:
