Question
Q1: A) : Oxygen (A) is diffusing through nondiffusing carbon monoxide(B) . The
total pressure is 1*10 N/m' and the temperature 298 k. The partial pressure of
oxygen at two phases 3.0 mm apart is respectively 12000 and 7500 N/m. The
diffusivity of the mixture is 1.78 *10 * m'/s. Calculate the rate of diffusion of
oxygen in kmol/s through each square meter of the two planes.
(8): Recolculate the rate of diffusion of oxygen (A) through a mixture of methan
(B) and hydrogen (C) as a non diffusing gas in the volume ratio 3:1. The diffusivities
DorH: = 7.99 * 10* m/s, DorcHa 1.68 10 m'/s
are assumed to be:
