Unformatted text preview: Review Sheet Exam 1 CH302 Quy Textbook Chapters for Exam 1: Chapter 16 sections 10 & 11, Chapter 17 (no section 8), Chapter 6 Background Material: you should know the basic thermodynamic relationships from Chapter 9 and 10, especially the relationship between free energy, enthalpy and entropy, G = H T S, for phase changes and the general concept of what it means to have a spontaneous process. Chapter 16 Physical Equilibrium. Know the proper name and verb for the process. The forward direction is endothermic for each Melts Vaporizes Sublimes Solid Liquid Liquid Gas Solid Gas Freezes Condenses Deposits Vapor Pressure. Know what vapor is and that vapor pressure increases with temperature. The relationship between a liquids vapor pressure and its temperature is nonlinear, they can be calculated using the Clausius-Clapeyron equation. H vap is the enthalpy of vaporization and is the enthalpy of boiling at the normal boiling point. Know that the normal boiling point is ALWAYS at 1 atm (760 torr) by definition. Phase diagrams. Plots of Pressure (y) vs Temperature (x) for all practical ranges of each. T Know what phases exist at each lettered point: A solid, B liquid, C gas, and the others. Know that the gas-liquid line has a finite end point but the solid-liquid line does not. Chapter 17 Dissolution. A solute dissolves in a solvent to make a solution. A solution is homogeneous. There are many ways to quantify the concentration of a solution. Know what they mean and how to convert from one to the other. Of major importance are molarity, mole fraction, mole percent, ppm (and cousins)....
