Question

Determine the sign of ΔS° for each of the following: I.C₆H₆(s)→ C₆H₆(l) II.2 SO₂(g)+ O₂(g)→ 2 SO₃(g)

Quizplus · Accepted Answer

For I, the transition from solid to liquid (melting) increases disorder, leading to a positive ΔS°. For II, the reaction reduces the number of gas molecules from 3 to 2, decreasing disorder and resulting in a negative ΔS°.
