The boiling points for pure water and pure toluene are 100°C and 110.6°C respectively. Toluene and water are completely immiscible in each other. A well agitated equimolar mixture of toluene and water are prepared. If, at a total pressure of one standard atm. exerted by the vapours of water and toluene, the mole fraction of water Xw in the vapour phase satisfies

The boiling points for pure water and pure toluene are 100°C and 110.6°C respectively. Toluene and water are completely immiscible in each other. A well agitated equimolar mixture of toluene and water are prepared. If, at a total pressure of one standard atm. exerted by the vapours of water and toluene, the mole fraction of water Xw in the vapour phase satisfies

Xw = 0.5

Xw = 1.0

0.5 < Xw < 1.0

0 < Xw < 0.5

Xw = 0.5

Xw = 1.0

0.5 < Xw < 1.0

0 < Xw < 0.5

Its molecular size is very small

Forces operative between its molecules are negligible

Its critical temperature is more than 0°C

It gets solidified directly without becoming liquid
