Determining the boiling point of a binary mixture is relatively straightforward if one has a Txy diagram (e.g., Figure 6.4-1). However, it is easy to make a mistake when reading such diagrams, and these mistakes can be costly. What if we dont have a Txy diagram? If one has a binary mixture that follows Raoults law, equation 6.4-9 can be used to estimate the boiling point for the mixture.

8. Determine the boiling point (P=1 atm) of a liquid mixture that is 40% benzene and 60% p-xylene on a molar basis. Report your answer in C.

9. Determine the boiling point (P=10 atm) of a liquid mixture that is 40% benzene and 60% p-xylene on a molar basis. Report your answer in C.

10. Describe how one could create the bubble point curve (i.e., bottom curve) on a Txy diagram such as the one shown in Figure 6.4-1. Estimate how long it would take you to create such a curve.
