The diagram below represents a large-scale fractional distillation plant used to separate the components A, B, C and D in a mixture

The components have the following average relative molecular masses not necessarily in that
order; 282, 184, 44 and 128.
(i) What is the physical state of B at the position marked Q?
(ii) Which component has an average relative molecular mass of 128? Explain
(iii) State with a reason whether C is pure or impure
(iv) Explain how the mixture is separated into its components
(v) Name two naturally occurring mixtures that are separated using this process

Answers

(i) Gas /vapour

(ii) B - It has the second lowest boiling point thus second lowest molecular mass

(iii) C is impure since it boils over a range of temperature

(iv) It is boiled heated and the vapour of the components condense at different temperatures

(v) - Liquid air
- Crude oil
