Answer the following statement(s) true (T) or false (F)
A. When a mixture is in vapor-liquid phase equilibrium, the chemical potential of all of the components in a phase must be the same.
B. Another name for the chemical potential of component i is the partial molar Gibbs free energy of component i.
C. When a mixture is in vapor-liquid phase equilibrium, the chemical equilibrium condition requires that no molecules are transferred between the liquid and vapor phases.
D. All of the above are true.
E. None of the above are true
A. Incorrect. At VLE, the chemical potential of an individual component in the liquid must be equal to the chemical potential of that component in the vapor.
B. Correct. The chemical potential is defined this way.
C. Incorrect. When in chemical equilibrium, there must be no NET movement of molecules. For example, if two molecules of (1) vaporize, two other molecules of (1) must condense.
D. Incorrect. At least one is false.
E. Incorrect. At least one is true.
