Question

Solution a and b mix to form warm solution which deviation it shows

Answer 1

pls tell what is a and b

Answer 2

On mixing A and B , the solution becomes warm.

This means heat released in formation of new bonds between A and B molecules is more than the heat absorbed for the breaking of molecules of A and B .

Therefore , the vapour pressure of the solution is reduced and thus the mixture shows negative deviation from Roult's law .
