We are given 50% benzene and 50% toluene contained in a cylinder with a pressure of 39.36 in Hg abs. The temperature at which a two-phase system can exist will have to be established. We need to construct a T-x-y diagram at 39.36 in Hg abs as constant pressure and observe the trend of the concentration of the two compounds, from there we can see that there is an intersection between the two compounds, this is where a two-phase system exists in a particular condition, at a certain temperature.
