In an air/carbon dioxide mixture at 298K and 202.6 kN/m², the concentration of CO₂ at two planes 3 mm a part are 15% and 25%. The diffusivity of CO₂ at 101.3 kN/m²is 1.64x105 m²/s. Calculate the rate of transfer of CO₂ across the two planes assuming : 1. Equimolecular counter diffusion.- 2. Diffusion of CO₂ through a stagnant air layer.
