An aqueous solution of methanol in water has vapour pressure

A

equal to that of water

B

equal to that of methanol

C

more than that of water

D

less than that of water

Text Solution

Verified by Experts

Methanol being more volatile than water, the solution of methanol in water will have more vapour pressure than water. Alternatively, `CH_(3)OH-H_(2)O` forms a non-ideal solution showing `+ve` deviation from Raoults' law. Hence, the solution has higher vapour pressure than that of pure components.
