The water-gas shift reaction is important in several chemical processes, such as the production of H2 for fuel cells. This reaction can be written as follows: H2(g) + CO2(g) = H20(g) + CO(g) with K = 0.106 at 700 K. If a mixture of gases that initially contains 0.632 M CO2 and 0.570 M H2 is allowed to equilibrate at 700 K, what is the final concentrations of CO?
