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 25⁰C.
(Given, vapour pressure data at 25⁰C benzene = 12.8 kPa, toluene = 3.85 kPa)

The vapour will contain a higher percentage of toluene

The vapour will 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
