Kinetic analysis of a model of the consecutive autocatalytic reaction has been carried out and the results of this analysis have been applied to the description of reduction of transition metal oxides. The proposed model is compared with the consecutive noncatalyzed reaction and the consecutive reaction in which the second step is limited by the nucleation process. It is shown that different mechanisms of the reduction can be distinguished on the kinetic bases.
