Mathematic modeling of со oxidation reaction rate self-oscillations over metallic catalysts

The mathematical model of $\mathrm{CO}$ oxidation reaction rate self-oscillations over metallic catalysts is considered. The dependence of reaction rate constant on the surface concentrations of reactant substances is included in the model. The feedback of such type can lead to the appearance of selfoscillations. The model considered is a multiparametric system of two ordinary differential eguations. The region of parameters which lead to self-oscillations is found by numerical and analytical methods. The influence of parameters on the properties of self oscillations has been studied.
