Question

(i) An aqueous solution of ethanol in water has vapour pressure :
(a) equal to H2O
(b) equal to ethanol
(c) more than water
(d) less than that of water.​

Answer 1

Answer:

more than water

Explanation:

The vapour pressure of an aqueous methanol solution is more than that of water but less than that of methanol. This is due to solute-solvent interaction is more due to the formation of hydrogen bonding than methanol but less than water.

Answer 2

The vapour pressure of an aqueous methanol solution is more than that of water but less than that of methanol. This is due to solute-solvent interaction is more due to the formation of hydrogen bonding than methanol but less than water.

(c) more than water
