A and B liquids on mixing produved warm solution.which type of deviation is there and why?

answered-by-expert Expert Answer

Solution becomes hot means heat is given out and it is a exothermic reaction. So H is negative or the intermolecular attraction of reactant A-A&B-B is> A-B interaction in solution. it will show positive deviation.
