Question

Sugars can be digested aerobically (with oxygen) or anaerobically (e.g. by yeast). During aerobic digestion, sugars react with oxygen to form carbon dioxide and water. During anaerobic digestion, sugars can be decomposed by enzymes to create carbon dioxide and alcohols.

Write the balanced chemical equation for the anaerobic digestion of 1 mole of glucose into carbon dioxide and ethanol C2H5OH(l).

For the above reaction at 25 ^oC, evaluate ∆H ^o (kJ), ∆S ^o (J/K), ∆G ^o (kJ), the number of moles of electrons transferred, and ∆E ^o (V).
