Benzene and naphthalene form an ideal solution at room temperature. For this process, the true statement(s) is(are) -

1. ΔG is positive
2. ΔS_system is positive
3. ΔS_surroundings = 0
4. ΔH = 0

Correct answer: ΔS_system is positive

Solution

In an ideal solution, the mixing of components increases randomness, leading to a positive entropy change (ΔS_system > 0). This is a characteristic of ideal mixing.
