Which of the following statements about the composition of the vapour over an ideal 1 : 1 molar mixture of benzene and toluene is correct? Assume that the temperature is constant at 25oC. (Given, vapour pressure data at 25oC, benzene = 12.8 kPa, toluene = 3.85 kPa)

Question

Which of the following statements about the composition of the vapour over an ideal 1 : 1 molar mixture of benzene and toluene is correct? Assume that the temperature is constant at 25^oC. (Given, vapour pressure data at 25^oC, benzene = 12.8 kPa, toluene = 3.85 kPa)

The vapour eill contain equal amounts of benzene and toluene.

Not enough information is given to make a prediction.

The vapour will contain a higher percentage of benzene.

The vapour will contain a higher percentage of toluene
