Interpretation:
The reason for the more efficiency of the packed column as compared to the unpacked column should be determined.
Concept introduction:
A technique used to separate various components or a fraction from mixture based on their volatilities is called fractional distillation. The fractional distillation is used to separate different components of the mixture if boiling point difference is less than
