Question #223907

Derive the equation for the partial pressure distribution of A and B for diffusion of A through non-diffusion B considering the point z-0 to z-z where the partial pressure of A is PA?

Expert's answer

Where:

D AB = molecular diffusivity of A in B

P T = total pressure the system

R = universal gas constant

T = temperature of system in absolute scale

z = distance between A and B across the direction of diffusion

P A1 = partial pressure of A at point 1

P A2 = partial pressure of A at point 2
