Chapter 18, Problem 66GQ

Yeast can produce ethanol by the fermentation of glucose (C₆H₁₂O₆), which is the basis for the production of most alcoholic beverages.

C₆H₁₂O₆(aq) → 2 C₂H₅OH(ℓ) + 2 CO₂(g)

Calculate Δ_rH°, Δ_rS°, and Δ_rG° for the reaction at 25 °C. Is the reaction product- or reactant-favored at equilibrium? In addition to the thermodynamic values in Appendix L, you will need the following data for C₆H₁₂O₆(aq):

Δ_fH° = −1260.0 kl/mol; S° = 289 J/K · mol; and Δ_fG° = −918.8 kl/mol.
