Which of the following sets of conditions could exist when two liquids that are completely miscible in one another are mixed?

▸

Δ*H*_{soln}> 0, entropy of system decreases

▸

Δ*H*_{soln}≈ 0, entropy of system decreases

▸

Δ*H*_{soln}≈ 0, entropy change of system ≈ 0

▸

Δ*H*_{soln}≈ 0, entropy of system increases

▸ None of these choices is correct.
