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

ANS:A - concentrations

In an interphase mass transfer process, the condition for equilibrium corresponds to equality of chemical potentials. Chemical potential is a thermodynamic property that represents the potential energy of a substance per unit quantity. At equilibrium, the chemical potential of a substance must be the same in both phases involved in the mass transfer process. This ensures that there is no net transfer of mass between the phases. Therefore, in an interphase mass transfer process, the equilibrium state corresponds to the equality of chemical potentials.
