A mixture of toluene,ethylbenzene and water is subjected to flash distillation of compostion on mole basis,30%,40%,30% respectively.Assuming mixture of tolune and ethyl benzene obey's Roult's law and that hydrocarbons is completely immicible with water,calculate the temp. and composition of liquid&Vapor phase at Bubble and at dew point.
Note:
Temp. in degree C and vapor pressure in mmHg.
