Question

For an ideal solution, the correct option is:

पर्याय

• Δ_mix S = 0 at constant T and P.

• Δ_mix V ≠ 0 at constant T and P.

• Δ_mix H = 0 at constant T and P.

• Δ_mix G = 0 at constant T and P.

Answer 1

Δ_mix H = 0 at constant T and P.

Explanation:

No enthalpy change on mixing: Δ_mix H = 0

No volume change: Δ_mix V = 0

Entropy of mixing is positive: Δ_mix S > 0

Gibb’s free energy of mixing is negative: Δ_mix G < 0
