Question

If heat is supplied to the stillpot too rapidly, the ability to separate two liquids by fractional distillation may be drastically reduced. In terms of the theory of distillation presented in the discussion, explain why this is so.

Answer 1

Answer: The boiling points of the two liquids are quickly exceeded

Explanation:

Fractional distillation is a method of separating a mixture of liquids where each has different boiling points.

To therefore obtain individual fractions, temperature rise of the mixture must be gradual, otherwise the boiling points of the two liquids will be quickly exceeded making collection of each fraction impossible.
