1. Molecular Diffusion in Gases (Diffusion Flux and Effect of Temperature and Pressure) Equimolar counterdiffusion is occurring at steady state in tube D.11 m long containing N2 and COgases at a total pressure of 1.0 atm absolute. The partial pressure of N2 is 80 mm Hg at one end and 10 mm at the other end. Predict the DAR by the method of Fuller et al. way Calculate the flux (N) in kg mol/s.m at 298 K for N2. (Repeat at 473 K. Does the flux increase? Repeat at 298 K. but for a total pressure of 3.0 atm absolute. The partial pressure of Nz remains at 80 and 10 mm Hg, as in part (a). Does the flux change
