Chem 204–Lecture 1 I am very sorry to miss the first lecture of the semester. It obviously looks very bad! Fog socked in the airport. No flights into Willard from either Dallas or Chicago, on 1/18. Prof. Murphy will give you a quick intro into materials in Chapter 8. Sections 1 5 I will have more details on Thursday, but also will have some in this file. (either .ppt or .pdf)

Lecture 1 –page 2 Consider a system in dynamic equilibrium, where the rate of evaporation equals the rate of condensation. The vapor or gas above the condensed phase (either solid or liquid), in terms of pressure will be constant if the system is closed. So A(gas) A(solid or liquid), and the relative amounts of both are constant for a give temperature and pressure.

Lecture 1 –page 3 What’s happening thermodynamically is that the free energy of the vapor and the condensed phase are equal. That is: Δ G vap = G mole (gas) – G mole (c.p) = 0 The Δ G vap represents the free energy of
