Chemistry questions and answers. A key step in the extraction of iron from its ore is FeO (s) + CO (g) = Fe (s) + CO2 (g) Kp = 0.404 (1000°C) At equilibrium, in the presence of excess FeO (s) and Fe (s), the partial pressures of CO (g) and CO2 (g) are 2.50 atm and 1.01 atm, respectively. If the partial pressure of CO2 (g) is suddenly decreased ...
