BMB428 Dr. Song Tan Physical Chemistry with Biological Applications Fall 2007 (edited 9/26/06) Problem Set 6: Enthalpy, Thermochemistry & more Math Due Sept 18, 2007 Enthalpy 1. We can define a useful quantity, enthalpy, as HUP V =+ (a) Prove that () H V T = 0 for an ideal monoatomic gas. (b) For a real gas, would H V T = 0? For this problem, assume that the real gas follows the equation PV nb nRT = 2. 1 liter of a fixed amount of an ideal monoatomic gas is allowed to expand at constant temperature from 3 atm to a final pressure of 1 atm. What is H if (a) the process is performed reversibly, (b) the process is performed irreversibly. 3. From the information in Table 3-3 (attached), calculate the enthalpy change (at standard temperature and pressure) for the following reactions. In both reactions, the sugar is glucose. (a) C 6 H 12 O 6 (s) + 6O 2 (g) –> 6CO 2 (g) + 6H 2 O (l) (b) C 6 H 12 O 6 (s) + 3O 2 (g) –> 6CO (g) + 6H 2 O (l) (c) Is aerobic or anaerobic respiration more energy efficient?
