If the overall mixture is 20% by mole R-245fa, will the mixture exist in one phase or multiple phases in equilibrium at 240 K and 0.1 bar according to the model? If the mixture does exist in multiple phases, what is the composition of the equilibrium phases?
Consider a model that predicts the behavior of the R-245fa (1) + isopentane (2) system at two pressures shown in the figure.
