Question
1. Does the vapor pressure of a compound increase or decrease with increasing mole ratio?
2. What is true about the vapor pressure above a mixture of two hydrocarbons in a distillation apparatus up to normal boiling point of the mixture, assuming an equimolar mixture of the two compounds?
-Both compounds will be present, but the vapor will contain less of the compound with the higher boiling point
-Only the compound with the lower boiling point will be present
-Equimolar amounts of each compound will be present in the vapor as well
-The total vapor pressure will be equal to the difference between the vapor pressures of the two components
3. Why is fractional distillation usually preferred over simple distillation when separating a mixture of liquids?
-Fractional distillation usually results in a much more complete separation of liquids than simple distillation although it is difficult to achieve 100% separation in either
-Simple distillation never takes place in a vacuum while fractional distillation does, resulting in a more complete separation when using fractional distillation
-Fractional distillation is much easier to complete than simple distillation
-Fractional distillation always results in a complete separation of the liquids while simple distillation never separates the liquids 100%
