Which of the following properties of the system would you expect to change as a result of this heating?
A system is in vapor-liquid-liquid equilibrium. One liquid phase contains 96% A and 4% B. The other liquid phase contains 99% B and 1% A. The vapor phase contains 43% A and 57% B. All compositions are on a molar basis. A small amount of heat is added to the system. At the end of the heating, the system is again in vapor-liquid-liquid equilibrium and still at the original system pressure. A. The temperature B. The mole fraction of A in the first liquid phase C. The mole fraction of A in the vapor phase D. The mass of the vapor phase E. All of the above
