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°C. (Given, Vapour Pressure Data at 25°C, benzene = 12.8 kPa, toluene = 3.85 kPa)
1. The vapour will contain a higher percentage of benzene.
2. The vapour will contain a higher percentage of toluene.
3. The vapour will contain equal amounts of benzene and toluene.
4. Not enough information is given to make a prediction.
