1 Chemistry 2290, Winter 2009, G. Schreckenbach Practice problems –3– Some practice problems from Atkins/ de Paula, 8 th edition: Second Law – Entropy Changes Out of the Discussion Questions for chapter 3: D 3.1, 3.2 Out of the Exercises for chapter 3: E3.1 to 3.7, 3.13, 3.15 For some of these questions, it may be necessary to look up the heat capacity. Out of the Problems for chapter 3: P3.1 to P3.6, P3.9 Atkins’ “Problems” are by assumption a bit more complex and complicated than the “Exercises”. Some practice problems from Atkins/ de Paula, 7 th edition: Second Law – Entropy Changes Out of the Discussion Questions for chapter 4: D 4.1a, 4.2b Out of the Exercises for chapter 4: E4.4 to 4.17, 4.23, 4.24, 4.26 For some of these questions, it may be necessary to look up the heat capacity. Out of the Exercises for chapter 4: P4.1 to P4.7 Atkins’ “Problems” are by assumption a bit more complex and complicated than the “Exercises”. More practice problems from Laidler/ Meiser (Problems adapted from Laidler Meiser Sanctuary, Physical Chemistry, 4 th ed., Houghton Mifflin) Second Law: Carnot Cycle 25. A reversible Carnot cycle that is based on an ideal gas operates between the two temperatures T h = 1000K and T L = 200K. The heat absorbed at the high temperature is 150 kJ. ? (Assume three significant figures.) (a) What is the thermodynamic efficiency of the machine? (b)
