A mixture undergoing multicomponent diffusion is analyzed through the Maxwell-Stefan approach. With regard to this approach which among the following statements are incorrect? The difference in the partial pressure of the Component A over a small distance ∆z (AB)is proportional to
(a) The molar concentration at the two points
(b) Length of the diffusion path
(c) Velocity at the point A
(d) Difference in the velocities at point A and B
The question was asked during a job interview.
My doubt stems from Multicomponent Diffusion topic in section Diffusion in Solids and Molecular Diffusion in Fluids of Mass Transfer
