Heat Created by Fermentation and Combustion of Glucose
Alcoholic fermentation by microorganisms involves the breakdown of glucose into ethanol and carbon dioxide.
C6H12O6 (s) -->; 2 C2H5OH (l) + 2 CO2 (g)
a) Calculate the amount of heat liberated in a yeast brew upon fermentation of 1 mol of glucose at 25 °C and 1 atm.
b) What fraction is the heat calculated in (a) of the amount of heat liberated by the complete combustion of glucose to CO2 and H20 (l) under the same conditions?
