Question

A mixture of compound A (lower b.p.) and compound B (higher b.p.) are distilled in a simple distillation. Between the 10th and 30th fractions, which one is more enriched in compound A orcompound B?

Answer 1

In the simple distillation of a mixture of compound A and compound B, the fractions between the 10th and 30th will be more enriched in compound A.

Step-by-step explanation:

In the simple distillation of a mixture of compound A (lower boiling point) and compound B (higher boiling point), the fractions between the 10th and 30th will be more enriched in compound A.

During distillation, the more volatile component, which has a lower boiling point, will vaporize first. As a result, the vapor phase will contain a higher mole fraction of compound A compared to the liquid phase.

Therefore, the 10th to 30th fractions, which are collected during the distillation process, will have a higher concentration of compound A.
