Two methods of determining coefficient of dif fusion of gases c. d. g. weight and freezing are described. With the first, c. d. are determined for the system of gases CO2-H2, CO2 N2, N2-H2, in the range of temperatures 20 800 C. A semi-empirical formula of dependence of c. d. g. on temperature is offered. A con nection between the coefficients of self diffusion and interdiffusion of gases is established. A comparison is made of the formula offered and Chepmen-Enskiys formula with the experimental data which shows a satisfactory concurrence of both formulas. Author
