If a two phase system is in physical equilibrium; then it means that, the_____________________?
Correct answer: B. All A., B. and C.
- A. Escaping tendency of each component from the liquid phase to the vapor phase is exactly
- B. All A., B. and C.
- C. Temperature of the liquid phase is equal to that of the vapor phase
- D. Total pressure throughout the liquid phase is equal to that throughout the vapor phase
- E. equal to that from vapor phase to liquid phase
Explanation
Physical equilibrium requires equal temperature and equal escaping tendency, or chemical potential, for each component in the two phases. These conditions correspond to statements A, B, and C, so E is the combined choice.
