Vapors move upward, so there is obstacles on an upward path due to the plates. i.e. pressure increases below the plates. So, the tendency of vaporization get decreases.

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

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

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.

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

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