C B C Consider the above figure on the left, in which a species is diffusing from phase & through a thin film of a different phase . The thickness of the thin film is f. An approximate concentration profile is also shown in the schematic. The diffusivity of the species in these two phases (a and B) are Da and DB, respectively. What will be flux (J) of the species in term of C and C ? You need Phase, a other parameters to solve the problem. It is up to you to figure them out.
