Compare the heat evolved at constant pressure per mol oxygen in the combustion of sucrose (C12H22O11) and palmitic acid (C16H32O2) with the combustion of a typical protein, for which the empirical formula is C4.3H6.6NO. Assume for the protein that combustion yields N2 (g), CO2 (g) and H2O (l). Assume that enthalpies for combustion of sucrose, palmitic acid, and a typical protein are 5647 kJmol-1, 10,035 kJ mol-1, and 22.0 kJ g-1, respectively. Based on these calculations, determine the average heat evolved per mol of oxygen consumed, assuming combustion of equal mols of sucrose, palmitic acid, and protein.
