In which reaction is ΔS° expected to be negative? A)2C₂H₆(g)+ 7O₂(g)→ 4CO₂(g)+ 6H₂O(l) B)Ga(l)→ Ga(s) C)H₂O(l)+ 2SO₂(g)→ H₂SO₄(l) D)CO₂(g)→ CO₂(s) E)all of above

Question

Quizplus · Accepted Answer

Each reaction listed involves a decrease in the number of gas molecules or the conversion of a substance from a more disordered state (gas or liquid) to a more ordered state (solid), both of which lead to a decrease in entropy (ΔS° < 0).
