Diffusion of CO₂ in a Binary Gas Mixture. The gas CO₂ is diffusing at steady state through a tube 0.20 m long having a diameter of 0.01 m and containing N₂ at 298 K. The total pressure is constant at 101.32 kPa. The partial pressure of CO₂ at one end is 456 mm Hg and 76 mm Hg at the other end. The diffusivity DAB is 1.67 x 10-5 m²/s at 298 K. Calculate the flux of CO₂ in cgs and SI units for equimolar counterdiffusion.
