What is true about modeling systems that show liquid-liquid equilibrium?
A. All models will provide a symmetric LLE dome, with the UCST at an equimolar composition. B. For immiscible systems, one can use the infinite dilution activity coefficient to estimate the compositions of the liquid phases that are in equilibrium. C. In modeling liquid-liquid phase equilibrium, one normally treats one of the phases using modified Raoult’s Law and the other phase as an ideal gas, if the pressure is below about 0.2 MPa. D. The pressure is the key modeling variable, since the LLE dome changes significantly with pressure. E. None of the above.
