2 An Ideal Solution That Has Dhsoln 0 Obeys Raoult S Law Which Suggests That The Vapor Pressure Of Each Liquid Compo 1 (76.38 KiB) Viewed 59 times

2. An ideal solution that has DHsoln = 0 obeys Raoult's law, which suggests that the vapor pressure of each liquid component in the solution is directly proportional to the mole fraction of that liquid in the solution. If DH soln <0 or > 0, the solution will deviate from Raoult's law, and the actual vapor pressure of such solutions will be either higher (positive deviation) or lower (negative deviation) than the one expected based on the Raoult's law. (a) Does a solution that has a negative DHsoln result in a negative or positive deviation? Does a solution with a positive DH soln result in a negative or positive deviation? (b) How does the relative strength of intermolecular forces between molecules in solution and in pure liquids influence the algebraic (+/-) signs of DH soln in solution formation?
