At 298 K and 1 atm total pressure, methane (A) is diffusing at steady state through non-diffusing
argon (B) and helium (C). At z₁ = 0, the partial pressures in atm are pa₁ = 0.4, PB1 0.4, and pc₁ = 0.2, and
at z₂ = 0.005 m, PA2 = 0.1, PB2 = 0.6, and pc2 = 0.3. The binary diffusivities are DAB = 2.02 × 10-5 m²/s, DAC
= 6.75 × 10-5 m²/s, and DBC = 7.29 × 10-5 m²/s. Derive the equation for NA and calculate it. Gas constant, R
= 8.206 × 105 m³ · atm/mol·K.
