Match List-I with List-II regarding the thermodynamic properties of solutions at constant temperature and pressure: List-I List-II A. Ideal solution I. _ mix H > 0 B. Solution showing positive deviation II. _ mix V C. Solution showing negative deviation III. _ mix S > 0 D. Spontaneous mixing of any two miscible liquids IV. _ mix H = 0 Choose the correct answer from the options given below:

Step-by-step solution

For an ideal solution, there is no change in enthalpy or volume upon mixing, so _ mix H = 0 (A matches IV). For a solution showing positive deviation from Raoult's law, the A-B interactions are weaker than A-A and B-B interactions, leading to an endothermic process ( _ mix H > 0 ) and an increase in volume (B matches I). For a solution showing negative deviation, A-B interactions are stronger, leading to a decrease in volume, so _ mix V The mixing of any two miscible liquids is a spontaneous process that increases
