Chapter 14, Problem 14.7P

PRACTICE 14.7 In the industrial synthesis of hydrogen, mixtures of CO and H₂ are enriched in H₂ by allowing the CO to react with steam. The chemical equation for this water-gas shift reaction is

$\text{CO}\left(g\right)+{\text{H}}_{\text{2}}\text{O}\left(g\right)\rightleftarrows {\text{CO}}_2\left(g\right)+{\text{H}}_2\left(g\right)$

What is the value of K_P, at 700 K if the partial pressures in an equilibrium mixture at700 K are 1.31 atm of CO, 10.0 atm of H₂O, 6.12 atm of CO_2, and 20.3 atm of H₂?
