While doing a distillation, Farha heats the mixture too fast, and the temperature rises too quickly. If the mixture is composed of two liquids, how will this likely affect the separation of the mixture?

Question

The liquids will be separated in reverse order.
Both liquids will evaporate and escape into the air.
The liquid with the lower density will be collected before the liquid with the higher density.
Some liquid with the higher boiling point will be collected along with the liquid with the lower boiling point.

Answer 1

If Farha heats the mixture too quickly during the distillation, the most likely outcome is that some liquid with the higher boiling point will be collected along with the liquid with the lower boiling point.

When the heating is too rapid, it can cause the vapors of the higher boiling point liquid to be carried over with those of the lower boiling point liquid, resulting in poor separation. Ideally, distillation relies on the gradual evaporation of the lower boiling point liquid first, allowing for a more effective separation based on differences in boiling points. A rapid increase in temperature disrupts this process, leading to a mixture of both liquids in the distillate.
