Correct Answer

(B) Chemical potentials

Explanation

Solution: In an interphase heat transfer process, the equilibrium state corresponds to equality of temperature in the two phases, while the condition for equilibrium in an interphase mass transfer process is equality of Chemical potentials In the context of mass transfer, equilibrium is achieved when the chemical potential of a substance is the same in both phases. This ensures that there is no net mass transfer between the phases, just as thermal equilibrium requires equal temperatures to prevent heat transfer. Therefore, the correct answer is Option B: Chemical potentials.
