A simple distillation was performed to separate a mixture containing both hexane and heptane. Explain why the observed starting vapor temperature in the simple distillation should be above the boiling point of hexane. Then, explain why if a fractional distillation was performed instead you would have a better separation (be sure to include how the fractionating column works in your explanation).
SIMPLE DISTILLATION 5. Which compound has a higher boiling point, ethanol or dimethyl ether? Explain 6. What are azeotropic mixture? 7. In today's setup what is the position of the thermometer? 8. What are two ideal solvents that we can separate using simple distillation?
6. Benzene and toluene form nearly ideal solutions. The boiling point of pure benzene is 80.1°C. Calculate the chemical potential of benzene relative to that of pure benzene when Xbenzene = 0.30 at its boiling point. If the activity coefficient of benzene in this solution were actually 0.93 rather than 1.00, what would be its vapor pressure?
Benzene and toluene form nearly ideal solutions. The boiling point of pure benzene is 80.1°C. Calculate the chemical potential of benzene relative to that of pure benzene when χbenzene = 0.30 at its boiling point. If the activity coefficient of benzene in this solution were actually 0.93 rather than 1.00, what would be its vapor pressure?
