Previous investigations on the equilibrium of the reactions between FeO and C and between CO and Fe are discussed briefly. It has been found experimentally that at temperatures under 700° the equilibrium constant,

p²CO

ζ= ------------------

pCO₂·_RT·760

of the reaction C+CO₂=2CO, does not coincide with that obtained from measurements of the equilibrium of the reaction between FeO and C and between CO and Fe. From both this and analytical data it would appear that in this equilibrium the C does not play a role as a definite phase. The most probable explanation of this phenomenon is the previously accepted surmise that the equilibrium is determined by the formation of carbide.
