As pressure increases the liquid composition is higher than vapor composition?

In another way, as pressure increases the separation becomes difficult. And relative volatility is also a separation.

Relative volatility means tendency to vaporise. In a simple way vaporisation is more easy under vaccum (low pressure) than any amount of positive means increase in pressure results decrease in volatility.

It can be like that: in high pressure molecules faces difficulty to separate cause the find less space in air.

Relative volatility=Pā/ (Pt-Pā). So, inversely proportional to the total pressure B.
