                   Résumé of earlier papers containing a full discussion of the reversible reaction 2CO=CO₂+C.  In the presence of finely divided metallic substances such as Fe heated at 445°, the velocity of the direct reaction is increased without modifying the proportions of the gaseous reagents in the final system when equilibrium is attained.  The experiments prove that the equilibrium ratio CO:CO₂ in contact with C is a function of the temperature, and the results are in general agreement with the laws respecting equilibria in gaseous systems.
