As the heat is evolved, the enthalpy change is negative. It must be exothermic and also shows negative deviation from raoult's law. Reason for negative deviation: The intermolecular forces between A-A and B-B are weaker than those between A-B. So, when u mix these kind of solutions, heat will be released and also it leads to decrease in vapour pressure. Sorry if any problem in my language
