1. The nomal boiling point of toluene is 110.6°C. What is its vapor pressure at this temperature 2 What effect does an increase in atmospheric pressure have on the boiling point of a l decrease?

Solution

1. Boilingpoint : The temperature at which, vapor pressure of liquid becomes equal to atmospheric pressure.

so that, vapour pressure of toulene at 110.6 c = atmospheric pressure (1 atm)

2. if atmospheric pressure increases, boiling point increases.
