A useful model of interfacial mass transport makes three assumptions:
(i) there is a difference between the concentrations of A at the interface, CA denoted CA in Phases I and II, respectively, and the bulk concentrations.
(ii) the rates of transfer in each phase are proportional to the differences between the bulk an interfacial concentrations:
(iii) the interfacial concentrations are in equilibrium:
(A) Show that the equation
(B) Find the limit of Km in the following cases:
(C) What is the physical significance of the two limits in part (B)?
