Question:
Why is the vapour pressure of an aqueous solution of glucose lower than that of water?
Solution:
Example of water and glucose can be taken for explaining this. In water, the surface of the liquid will be occupied by the water molecules. When we add glucose into it,
some of the surfaces will be occupied by the glucose molecules. Therefore the number of a solvent molecule will escape from the surface and thus vapour pressure also
get reduced.
