Kinetics of reactions betwwen CO-CO2 mixtures and liquid iron were investigated at 1 843 K using the cold crucible technique and the concentration changes of C and O were analyzed using non-linear kinetic equations based upon independent reactions in the systems. The carbon or oxygen concentration changed against the chemical potential gradient in the initial stage of the reactions. It was proved that such concentrations changes were contolled only by interfacial reactions. The concentration changes in the whole process were succesfully reproduced by nonlinear equations based upon the two independent reactions in which the nonlinear reaction CO(g) = C+O was included. It has been shown that there are always some combinations of independent reactions which can describe the chemical changes in irreversible processes from the macroscopic point of view.
