CHM 139F Tutorial 11 Entropy and free energy These questions are about entropy and free energy. The material is largely to be found in sections 8.13 and 8.14 and in parts of Chapter 17 of McMurray and Fay (Fourth edition) or Chapter 16 (Fifth edition). You should try to do the following questions: Fourth edition: 8.31, 8.32, 8.33, 17.20, 17.21, 17.22, 17.50, 17.51, 17.70, 17.84, 17.85 and 17.90 or Fifth edition: 8.33, 8.34, 8.35, 16.20, 16.21, 16.22, 16.52, 16.53, 16.72, 16.86, 16.87 and 16.92

Unformatted text preview: The Gibbs free energy of a pure substance increases as the pressure increases and the rate of increase is higher for gases than for liquids and is usually higher for liquids than for solids. By sketching the Gibbs free energy vs pressure curves for a pure substance in the solid, liquid and gas phases, explain why solids are usually more stable at high pressures, liquids at intermediate pressures and gases at low pressures....
