Vacuum distillation increases the relative volatility of the key components in many application
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Relative volatility of binary liquid mixtures increases above 1, separation by distillation becomes progressively easier. When a binary liquid mixture is distilled, complete separation of the two components is rarely achieved.

Detailed explanation-2: -Vacuum distillation is an important process in the chemical and pharmaceutical industry. But it is employed in many other sectors, too. For example, in beverage and food production to extract plant essences, or to separate long-chain hydrocarbons in oil refineries.

Detailed explanation-3: -The boiling points and vapor pressures of each individual substance indicate the relative volatility of a chemical to the rest of the mixture. Determining the vapor pressures and, in turn, the relative volatility, will indicate how difficult it will be to separate the substances in the mixture via distillation.

Detailed explanation-4: -Thus if the relative volatility between two components is equal to one, separation is not possible by distillation. The larger the value of , above 1.0, the greater the degree of separability, i.e. the easier the separation.
