Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is option 3.
Key Points
- For two liquids (A and B) to form an ideal solution, they must follow Raoult’s Law and exhibit ideal mixing behavior. This requires:
- ΔH_mix (Enthalpy of Mixing) = 0
- In an ideal solution, the intermolecular forces between A-A, B-B, and A-B are nearly identical.
- No heat is absorbed or released upon mixing, meaning the enthalpy change (ΔH_mix) is zero. Hence option 3 is the correct answer.
- ΔS_mix (Entropy of Mixing) > 0
- Entropy increases due to greater randomness when two liquids mix.
- ΔG_mix (Free Energy of Mixing) < 0
- A spontaneous mixing process requires negative free energy change (ΔG_mix).
