A sealed reaction vessel initially contains 1.217×10-2 moles of water vapor and 1.490×10-2 moles of CO(g).

H2O(g)+CO(g)<>H2(g)+CO2(g)

After the above reaction has come to equilibrium, the vessel contains 8.733×10-3 moles of CO2(g). What is the value of the equilibrium constant Kc of the reaction at the temperature of the vessel?
