Question

The value of ΔS° for the oxidation of solid elemental sulfur to gaseous sulfur trioxide, 2S (s,rhombic)+ 3O₂(g)→ 2SO₃ (g) Is ________ J/K ^∙ mol.

Quizplus · Accepted Answer

The reaction involves a decrease in the number of moles of gas (from 3 moles of O2 to 2 moles of SO3), which typically results in a decrease in entropy (ΔS°). Therefore, ΔS° is negative.
