An equilibrium mixture of
CO(g)+H2O(g)⇌CO2(g)+H2(g)
present in a vessel of one litre capacity at 815∘C was found by analysis to contain 0.4 mole of CO, 0.3 mole of H2O, 0.2 mole of CO2 and 0.6 mole of H2.
(a) Calculate KC .
(b) If it is derived to increase the concentration of CO to 0.6 mole by adding CO2 to the vessel, how many mole must be added into equilibrium mixture at constant temperature in order to get this change ?
