The topics covered are thermochemistry, phase equilibrium, and thermodynamics of mixtures. There will NOT be any problems on chemical equilibrium in Exam 2. If you understand how to solve every homework problem you should not have any problems with this exam. 1. Two moles of liquid A are mixed with 1 mole of liquid B and form an ideal solution. The process is preformed at constant temperature T and pressure P. A. What is the change of entropy as a result of mixing? B. What is G? C. What is the heat q released as a result of mixing? D. What is the difference, V, between the volume of the mixture and the total volume of separated A and B?
