Problem 87

As O2(l) is cooled at 1 atm, it freezes at 54.5 K to form solid I. At a lower temperature, solid I rearranges to solid II, which has a different crystal structure. Thermal measurements show that H for the phase transition is 743.1 J/mol, and S for the same transition is 17.0 J/K mol. At what temperature are solids I and II in equilibrium? 8

Friday, October 28, 2016 Weeks 8/9 Notes CHE 152 - Thermochemistry • Thermochemistry is the relationship between energy and chemical processes - energy is the capacity to do work (w) or transfer heat (q) • E= w + q • The Law of Conservation of Energy: Energy is neither created nor destroyed in a chemical process - energy can only be transferred from one object to another • a system is the portion of the universe we are studying, for example, a reaction • the surroundings are everything that the system can exchange energy with - theoretically, this is the rest of the universe - practically, this is the container and the solution inside it • Energy exchange: energy gained or lost by the system must be gained or lost by t
