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?
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
