Is the combustion of ethane, C₂H₆, product-favored at equilibrium at 25°C?
C₂H₆(g) + 7⁄2 O₂(g) → 2 CO₂(g) + 3 H₂O(g)
Answer the question by calculating the value of ΔS°(universe) at 298 K, using values of Δ_fH° and S° in Appendix L. Does the answer agree with your preconceived idea of this reaction?
