22. Alcoholic fermentation by microorganisms involves the breakdown of glucose into ethanol and carbon dioxide by the reaction glucose(s) 2 ethanol(l) + 2 CO2(8) (a) Calculate the amount of heat liberated in a yeast brew upon fermentation of 1 mol of glucose at 25C, 1 atm. (b) What fraction is the heat calculated in part (a) 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 Problem 21? 20. One mole of liquid H20 at 15C is mixed with 1 mol of liquid H,0 at 65C. The pressure is kept constant and no heat is allowed to leave the system. The process is adiabatic. Calculate the final temperature for the system. 20. One mole of liquid H20 at 15C is mixed with 1 mol of liquid H20 at 65C. The pressure is kept constant and no heat is allowed to leave the system.
