Specially formed mixtures of isotopes of chemical elements have better consumer properties than their natural counterparts. Therefore, the development of methods for increasing the efficiency of the known methods for producing of isotope materials is relevant. It is known that the chemical bond is formed only in the singlet state of the spins of valence electrons of the reagents. On the basis of the known representations about dispersion of spin projections on the coordinate axes and the molecular-kinetic theory of gases was obtained an expression for the constant of the chemical reaction between the radicals occurring in the magnetic field. This expression allows calculating the reactivity of the isotopic modifications of radicals. Plasma allows to transfer many of the compounds in the gas phase. It is known that a significant part of particles in low temperature plasma is in a radical form. The equations of chemical kinetics for describing the process of oxidation of the carbon isotopes in argon-oxygen plasma occurring in an external permanent magnetic field were written in the work. It was shown that the efficiency of plasma process of isotopes separation can be increased only under insufficient oxygen relative to the stoichiometric value. These equations of chemical kinetics of processes occurring in the plasma process of incomplete oxidation of carbon isotopes needed to find experimental conditions that provide the maximum isotope effect in a magnetic field
