Which of the following thermodynamic and physical conditions rigorously apply to a theoretically per — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

Ideal solutions perfectly obey Raoult's law (A), meaning observed Vapor Pressures and Boiling Points match theoretical calculations (B). Because A-A, B-B, and A-B interactions are essentially identical in magnitude, no heat is evolved/absorbed ($\Delta H_{mix} = 0$) and volume is conserved ($\Delta V_{mix} = 0$) (D). Option C describes a non-ideal positive deviation, not an ideal solution.
