question

At steady state conditions, Oxygen (A) diffuses through Nitrogen (B).Consider the nitrogen asnondiffusing. The temperature is 0°C and the total pressure is 1 × 10^5 N / m^2.The partial pressure of oxygen at two locations, 2.2 mm apart is 13500 and 6000 N / m^2. The diffusivityis 1.81 × 10^-5 m^2 / sec. (I)Determinethe diffusion rate of oxygen. (II) Determine the diffusion rate of oxygen (A) using as the nondiffusing gas a mixture of nitrogen (B) and carbon dioxide(C) in a volume ratio of 2:1. The diffusivities are D_(_O)2- (N)2= 1.81 × 10^-5 m^2 / sec, D_(_O)2- (CO)2= 1.85 × 10^-5 m^2 / sec.
