When H2O and CO react at 979°C, the products are CO2 and H2. The equilibrium constant (in terms of equilibrium concentrations of reactants and products) for the reaction below is 0.70 at 979°C.
CO(g) + H2O(g) → CO2(g) + H2(g)
If the following concentrations are measured after the reaction reaches equilibrium, what is the concentration of CO(g) in the equilibrated mixture?
Component Measured equilibrium concentration
H2O(g) 0.751 M
CO2(g) 0.137 M
H2(g) 3.40 M
