The necessary condition for phase equilibrium in a multiphase system of N components is that the____________________?
Correct answer: A. Chemical potentials of a given component should be equal in all phases
- A. Chemical potentials of a given component should be equal in all phases
- B. Chemical potentials of all components should be same in a particular phase
- C. Sum of the chemical potentials of any given component in all the phases should be the same
- D. None of these
Explanation
Phase equilibrium requires equality of the chemical potential of each component in every phase: μᵢ^α = μᵢ^β = ... . Equality of all components within one phase is not required, because different components normally have different chemical potentials.
