Question

On mixing liquid X and liquid Y, volume of the resulting solution decreases. What type of deviation from Raoult's law is shown by the resulting solution? What change in temperature would you observe after mixing liquids X and Y?

Answer 1

On mixing liquid X and liquid Y, the volume of the resulting solution decreases means it is Negative deviation of Raoult's law. There is an elevation of boiling point occurs i. e., the temperature of the solution increase it means $\delta H=-ve$. So it is an exothermic reaction.
