2. A mixture of Oz (A) and N2 (B) diffuses through the pores of a 2-mm-thick piece of unglazed porcelain at a total pressure of 0.1 atm and a temperature of 293 K. The average pore diameter is 0.1ụm, the porosity is 30.5%, and the tortuosity is 4.39. Estimate the diffusion fluxes of both components when the mole fractions of O2 are 80% and 20% on either side of the porcelain. The collision diameters for oxygen and nitrogen are 3.467 and 3.798 Å, respectively.
