Hydrogen gas is diffusing through air. Air has non-diffusing species: (1) 02, (ii) N2, and (iii) H2. Mole fraction are 02= 0.2, N2= 0.7 and H2= 0.1. Find diffusion coefficient of H2in air during...

Hydrogen gas is diffusing through air. Air has non-diffusing species: (1) 02, (ii) N2, and (iii) H2. Mole fraction are 02= 0.2, N2= 0.7 and H2= 0.1. Find diffusion coefficient of H2in air during steady state for temperature 300 K and pressure 4 bar. Diffusion coefficients of hydrogen in oxygen DH_02= 16 x 10-6m2/s at 273 K and 1 bar while in nitrogen DH_N2= 18 x 10-6m2/s at 300 K and 1 bar.
