The necessary and sufficient condition for equilibrium between two phases is_________________?
Correct answer: D. The chemical potential of each component should be same in the two phases
- A. The concentration of each component should be same in the two phases
- B. The temperature of each phase should be same
- C. The pressure should be same in the two phases
- D. The chemical potential of each component should be same in the two phases
Explanation
Phase equilibrium requires the chemical potential of every component to be equal in the coexisting phases, along with common thermal and mechanical equilibrium. Equal concentration is not necessary because partitioning between phases is generally different.
