The value of δs° for the oxidation of solid elemental sulfur to gaseous sulfur dioxide, s (s, rhombic) + o2 (g) → so2 (g) is j/k⋅mol. the value of s° for the oxidation of solid elemental sulfur to gaseous sulfur dioxide, s (s, rhombic) + o2 (g) so2 (g) is j/kmol. +248.5 +485.4 +11.6 -11.6 -248.5

Explanation:

You can calculate the entropy change of a reaction by using the standard molar entropies of reactants and products.

The formula is

The equation for the reaction is

                        S(s, rhombic) + O₂(g) ⟶ SO₂(g)

ΔS°/J·K⁻¹mol⁻¹         31.8            205.0      248.1

The difference probably arises for our use of different sources for the molar entropies.
