Explanation

Since water and toluene are immiscible, their vapor pressures add up independently. An equimolar mixture will exert a total vapor pressure of one atmosphere at a temperature between the boiling points of pure water (100°C) and pure toluene (110.6°C). Therefore, the boiling temperature of the mixture lies between 100°C and 110°C.
