An aqueous solution of methanol in water has vapour pressure

Answer»

equal to that of water
equal to that of methanol
more than that of water
less than that of water

Solution :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.
