A mixture of He and N2 gas is contained in a pipe at 298 K and 1 atm total pressure which is constant throughout. At one end of the pipe at point 1 the partial pressure of He is 0.6 atm and at the other end, 0.2 m away, the partial pressure is = 0.2 atm. 1. Calculate the flux of He at steady state if DAB of the He-N2 system is 0.684 x 10-4 m2 /s. R = 8.314 m3Pa/mol K. 2. Recalculate the flux of A assuming only molecular diffusion applies, i.e. ignore the bulk motion term.
