If all the components except 1 of the multicomponent diffusing mixture are inert, then what will be the expression for Diffusivity of component 1 in the mixture?
(a) D1m=(N1-Y1∑Nj)/(∑(YjN1-Y1Nj)/Dij)
(b) D1m=(Y1∑Nj)/(∑(YjN1-Y1Nj)/Dij)
(c) D1m=N1/(∑[(YjN1-Y1Nj)/Dij])
(d) D1m=(1-Y1)/(∑[Yj/Dij])
The question was asked during an online interview.
This interesting question is from Multicomponent Diffusion in chapter Diffusion in Solids and Molecular Diffusion in Fluids of Mass Transfer
