Step-by-step explanation
We know that the temperature at which vapour pressure of a liquid becomes atm. is called the boiling point of the liquid.
From the figure, we can clearly see that Graph I is for pure solvent whereas graph II is for solution. Hence the boiling point of solvent and solution are and respectively.
