Which statement is not correct if two immiscible liquids of mol. wt. A and B respectively are mixed in equal amount to have a mixture?
The total vapor pressure of the mixture is equal to the sum of the vapor pressures of the two pure components.
The mole fraction of each component is directly proportional to its molecular weight in the mixture.
The boiling point of the mixture is lower than the boiling points of its both components.
The partial vapor pressure of each component is proportional to its mole fraction in the mixture.
