Question

On which factor does vapour pressure of liquid at fixed temperature depend upon ?

(A) Nature of liquid
(B) Boiling point of liquid

(C) Number of moles of liquid (D) All of the given​

Answer 1

The vapor pressure for any liquid then depends only on the temperature and the IMF. As temperature increases, VP increases. Stronger IMF mean that it requires more energy to overcome the IMF and enter the gas phase. Thus, the rate of evaporation will be lower and the VP will be lower.
