Diffusion Coefficients: Ar
O2#gas-gas#100C to Xe#gas-gas#-73C
Binary diffusion coefficients for gas-gas, gas-liquid (dissolved gas in water), and liquid-liquid (solute at infinite dilution) systems. Gas-gas D in cm²/s at 1 atm across temperatures -73 to 400°C; gas-liquid D in cm²/s (~1e-5 scale); liquid-liquid in water D in m²/s (~1e-9 scale); liquid-liquid in organic solvents D in cm²/s (~1e-5 scale).
