Chapter 16Current LectureCHEM 1442 Study Guide and Learning Objectives (Silberberg 7/e) Chapter 12 Intermolecular Forces: Liquids, Solids and Phase Changes You will not be responsible for contents of Section 12.6 and Section 12.7. 1. Distinguish between intramolecular forces and intermolecular forces. 2. Know the names of the various phase changes: • fusion (melting) vs. freezing • vaporization vs. condensation • sublimation vs. deposition 3. For a given phase change, determine whether enthalpy increases or decreases. 4. Know and correctly use the following terms: • the heat of fusion (ΔH°fus) • the heat of vaporization (ΔH°vap) • the heat of sublimation (ΔHºsubl) 5. Understand heating-cooling curves and be able to calculate the amount of heat absorbed or released in phase changes. 6. Define and be able to apply the concepts of vapor pressure, volatility, boiling point, and normal boiling point. 7. Understand what phase diagrams represent. • Be able to identify each region in the phase diagrams of H2O and CO2 (solid, liquid, gas, supercritical fluid). • On a phase diagram, locate the triple point, critical point, normal melting point, and normal boiling point. • Use a phase diagram to describe phase changes. 8. Understand and be able to describe the different types of intermolecular forces, also called van der Waals forces:• ion-dipole forces • dipole-dipole forces These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.• hydrogen bonding • dipole-induced dipole • London dispersion forces 9. Be familiar with the concept of “polarizability”, and be able to use polarizability to predict the relative strengths of intermolecular forces. 10. Relate the following properties of liquids to their intermolecular forces: • surface tension • capillarity • viscosity • vapor pressure • boiling point and melting point 11. Understand how the macroscopic properties of water arise from its molecular properties. (IMPORTANT) Additionally in Exam 1, you will be tested for two Chapter 16 topics given in ALEKS “Chapter 12” homework assignment: They are • Predicting how reaction rate varies with pressure, concentration and temperature. • Calculating the reaction rate of one reactant from that of another.
