Stefan and Maxwell explained the diffusion of A through B in terms of the driving force d_cA, the resistances that must overcome the molecular mass transfer, and a proportionality constant,
. The following equation expresses mathematically the resistances for an isothermal, isobaric gaseous system:

Wilke³³
extended this theory to a multicomponent gas mixture.

The appropriate form of the Maxwell-type equation was assumed to be

Using this relation, verify equation (24-49).
