Chapter 14, Problem 14.17P

PRACTICE 14.17 The H₂/CO ratio in mixtures of carbon monoxide and hydrogen( called synthesis gas) is increased by the water—gas shift reaction CO(g) + H2O(g) $\rightleftarrows$ CO₂(g) + H₂(g), which has anequilibrium constant K_c = 4.24 at 800 K. Calculate the equilibrium concentrations of CO₂, H₂, CO, and H₂O at 800 K if only CO and H₂O are present initially at concentrations of 0.150 M.
