Why does the insolubility of benzene and water in each other cause each liquid to exert its own vapor pressure when a mixture of benzene and water undergo steam distillation?
Homework Answers
When a mixture of two practically immiscible liquids like water and benzene are heated together, they get agiated and exposes the surface of each liquid to the vapour phase.As a consequence each constituent independently exerts its own vapour pressure as a function of temperature as if the other constituent were not present. Thus, during steam distillation of water and bezene each liquid exerts its own vapour pressure.

Saturated liquid water at 10.0 MPa is throttled through a partially open valve (isenthalpic process) and discharged into a tank at a pressure 0.1 MPa adiabatically, aergonically, and without any change in its kinetic or potential energy. (NOTE: When the pressure on saturated liquid water is suddenly reduced in an adiabatic aergonic, steady flow process, part of the initial liquid is very quickly converted into a saturated vapor at the lower pressure, with the vaporization energy (heat of vaporization) coming...

Post Lab Questions Fermentation: 1. What physical property enables one to use distillation for the separation of ethyl alcohol enriched from the water mixture? 2 What is an Azeotrope? Explain how can azeotropes be used to purify mixtures? 3. Azeotropes are also defined as liquid mixtures having a vapor pressure at constant temperature, as a function of composition. Explain with your own words why vapor pressure depends on the composition of the mixture. 4 If the distillation temperature is different...

A mixture containing 42% benzene and 58% toluene by mass is fed to a distillation column. A second mixture is also fed to the distillation column and has a composition of 65% toluene and 35% acetone by mass. The flowrates of the mixtures are 2500 kg h1 and 1500 kg h1 respectively. An overhead distillate exit stream of 800 kg h-1 containing 23% acetone and a bottom exit stream of 25% benzene are produced. Determine the bottom exit flowrate and...
