Carbon monoxide and water vapor react to...

Carbon monoxide and water vapor react to give `Co_(2)` and `H_(2)` in a vessel of 2 L capacity at 1090 K . Equilibrium is established and the number of moles of various components is found to be 0.8,0.6,0.4 and 1.2 mol , respectively. Calculate `K_(c)` value. 1.2 mol by increasing the concentration of `CO_(2)` at the equilibrium , find the number of moles of `CO_(2)` to be added to the reaction mixture at the same temperature.
