glucose (C6H12O6) is converted into ethanol (C2H5OH) and carbon dioxide (CO2) in alcoholic fermentation.

a) Write a balanced chemical equation for alcoholic fermentation

b) Based on the equation, what would you expect ΔS°rxn to be? positive or negative? Explain.

c) Estimate ΔS°rxn and ΔH°rxn. By using the data
Substance ΔH° (kj/mol) S° (j/mol.K)
C6H12O6 -1273.3 212.1
C2H5OH -277.6. 160.7
CO2. -393.5. 213.8

d) What would you expect this reaction to be? never spontaneous, always spontaneous, spontaneous only at high temperatures, or spontaneous only at low temperatures? Explain.

e) Calculate ΔG°rxn at 150 °C.
