Explanation:
Distillation is defined as a process in which two liquids with a temperature difference less than 25^{o}C are boiled together. As a result, liquid with low boiling point vaporizes and collected in a separate container.
Hence, separation of both the liquids take place.
When we carry out slow distillation then both vaporization and condensation takes place simultaneously more effectively. Hence, an equilibrium is maintained.
And, when we do fast distillation then vapors do not condense as quickly as desired. Hence, liquids will not separate out easily.
