14. (b) In fact, only a fraction f of molecules M that are added to the system result in the creation of a vacancy. This has no consequence for the discussion presented here.

16. (a) Although there may be a net flux of mobile species with respect to the microporous material, one has to realize there is also a flux of vacancies. Because the mobile species and the vacancies are conjugated, the fluxes of the mobile species and vacancies exactly oppose each other. Thus, the average motion of the mixture of all mobile species, i.e. "real" and vacancies, is zero.
