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°C. (Given, vapour pressure data at 25°C, benzene = 12.8 kPa, toluene = 3.85 kPa)

पर्याय

• The vapour will contain a higher percentage of benzene.

• 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.

Answer 1

The vapour will contain a higher percentage of benzene.
