For the reaction CO2 (g) + H2(g) ↔ CO(g) + H2O(g) the value of K at 552°C is 0.137. If 3.0 moles of CO2, 3.0 moles of H2 , 1.5 mole of CO and 1.5 mole of H2O are initially present in a 1.0 L closed vessel, what are the actual concentrations of CO2, H2,CO and H2O at equilibrium

Here Kp = Kc  . Taking dissociation constant as a, ((3a)2/(3(1-a))2)=0.137
Solving for a, =0.27. Hence equillibrium concentrations of CO and H2O are 1.5+.81=2.31moles/L each and that of CO2  and H2 are 2.19moles/L each.
