How can the vapour pressure become equal to that of the atmosphere when the liquid and vapour phases of the soultion are in equilibrium?

Expert Answer:

 When a mixture starts boiling , the vapour does not, in general, have the same composition as the liquid. Instead, the substance with the lower boiling temperature (or higher vapor pressure) will have a vapour concentration higher than that with the higher boiling temperature, though both will be present in the vapour. And the same logic applies when the  mixture condenses.
