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

(C) What is the physical significance of the two limits in part (B)?
Q. Use of Halides of Boron? Boron trihalides of the type BX3 exist for all the four halogens. Boron trifluoride can be prepared on a large scale by the fluorination of boric ox
1 gm of a metallic oxide on reduction gives 0.68 gm of the metal. ans) Mass of metal/mass of oxygen=eq. mass of metal/eq. mass of oxygen. applying this we get .68/.32=x/8 x=1
