Abstract
In this work, we compiled and evaluated both self-diffusion and binary-diffusion coefficients D for gases as a function of temperature. In this paper, we provide recommended values for the diffusion coefficients at standard room temperature 298.15 K (D298) and standard atmospheric pressure (101.325 kPa). We also provide recommended expressions for the diffusion coefficients as a function of temperature.
