1.    A reaction that is representative of those in the glycolytic pathway is the catabolism of glucose by complete oxidation to carbon dioxide and water:

C6H12O6 (s) + 6O2 (g) → 6CO2 (g) + 6 H2O (l)

a.    Calculate ΔrHo298 for glucose oxidation.

Alcoholic fermentation by microorganisms involves the breakdown of glucose into ethanol and carbon dioxide by the reaction

C6H12O6 (s) → 2 C2H5OH (l) + 2CO2 (g)

b.    Calculate the amount of heat liberated in a yeast brew upon fermentation of 1 mol of glucose at 25 oC, 1 bar.

c.     What fraction is the heat calculated in part b of the amount of heat liberated by the complete combustion (reaction with O2) of glucose to carbon dioxide and liquid water at 298 K, calculated in part a.
