Question

When 1 mole of benzene is mixed with 1 mole of toluene? (vapour pressure of benzene – 12.8 kPa, Toluene = 3.85 kPa)

पर्याय

• The vapour will contain equal amount of benzene and toluene.

• Not enough information is given for prediction.

• The vapour will contain a higher percentage of benzene.

• The vapour will contain higher percentage of toluene.

Answer 1

The vapour will contain a higher percentage of benzene.

Explanation:

Because benzene has a higher vapour pressure than toluene, it produces more vapours.
