In a binary gas mixture containing A and B, If NA=-2NB, what will be the expression for NA?
(a) 2(D*(P1-P2))/RTL
(b) (D*(P1-P2))/RTL
(c) DP*(2RTZ)^-1*ln[(P-P1)/(P-P2)].
(d) 2DP*(RTZ)^-1*ln[(P-P1)/(P-P2)].
I got this question during an interview.
I would like to ask this question from Diffusion through Variable Area topic in section Diffusion in Solids and Molecular Diffusion in Fluids of Mass Transfer
