Question:

Calculate the standard molar entropy change, Δ_r S°, for each of the following reactions at 25°C:
(a) C(s) + 2 H₂(g) → CH₄(g)
(b) CH₄(g) + 1⁄2 O₂(g) → CH₃OH(ℓ)
(c) C(s) + 2 H₂(g) + 1⁄2 O₂(g) → CH₃OH(ℓ)

Verify that these values are related by the equation Δ_r S°(1) + Δ_r S°(2) = Δ_r S°(3). What general principle is illustrated here?
