When carbon monoxide is adsorbed on iron films at temperatures T greater than equivalent to 373 K carbon dioxide and carbon are formed. The Boudouard equilibrium is, however, not established at the chosen reaction conditions. In the presence of hydrogen the carbon monoxide adsorption leads to the formation of methane, carbon dioxide, and water. There is no correlation between the formation of water and of methane. The methane formation increases with both the increase in the total pressure and the increase in the partial pressure ratio p//H//2:p//C//O. The ratio of the partial pressures of CO, H//2, CO//2, and H//2O point to the establishment of the water gas equilibrium at medium temperatures.
