why it takes more time to distill out water than toluene?

Due to differences boiling point

Distillation is separation by component based on VAPOR PRESSURE AND NOT BOILING POINT.

Vapor pressure of toluene is much higher than water, and so it take longer hours to distill water than toluene.

Boiling point of toluene is greater than that of water, so water should distill first, not toluene.

water have more latent heat of vaporization than toluene....for same heat load...

water has lower boiling point(100deg) than toluene(110). one which has lower boiling point has also higher volatility and hence water can be easily separated using distillation.

Please be specific. water individually can not distill. From which solvent you want water to be distilled?

b.p of water is 100C b.p of toluene is 110C , they will form azetropes , so i would go for azetropic distillation or maybe extraction

in case of azeotrope only alternative is through azeotropic distillation ... extractive distillation s used when relative volatility is close to 1 and no of tray reqd r high
