CHAPTER OUTLINE

1. The speed of a reaction is dependent on temperature, which controls reaction rate. SECTIONS 16.1-16.2

2. Phases can be crystalline or amorphous.

3. Phase changes involve changes in order (entropy) and energy. SECTIONS 13.1

4. Specific heats measure energy changes within a phase. SECTION 3.7

5. Heats of fusion & vaporization measure energy of phase changes.SECTION 13.2

6. At every temperature there is an equilibrium between liquid & vapor,based on attractive forces. SECTION 13.4

7. Boiling occurs when vapor pressure equals atmospheric pressure. SECTION 13.4

8. Solutions can be made in any combintation of states.

9. As mixtures, solutions do not have fixed boiling points.

10. Solvation involves attractive forces and energy/entropy changes. SECTION 13.3 & 14.1

11. Solubility is affected by temperature and pressure. SECTION 14.2

12. The ion model explains the the electrical behavior of some solutions. SECTIONS 4.10-4.11

13. Nomenclature rules can be expanded to include polyatomic ions and hydrates. SECTION 5.5

14. Solution concentration can be expressed in percents of molarity. SECTIONS 14.3-14.4

CLOSED BOOK

interpret a demonstration about the speed of a reaction in terms of collsion theory and the influence of temeprature and concentration on reaction rate identify the energy, entropy, temperature, and state changes happening at each stage of a heating/cooling curve, including role of heats of vaporization & fusion and specific heat interpret an equilibrium vapor pressure diagram explain the effects of attractive forces and temperature on vapor pressure and boiling interpret a phase diagram connect altitude, air pressure, and boiling point qualitatively

OPEN BOOK

solve problems using heats of vaporization & fusion and specific heats solve for effects of altitude using p = e-h/7

Concentration Test Review (closed book except for Beer's Law problems & colorimeter work) Click here for practice problems.

KNOW	compare the boiling behavior of solutions vs. pure liquids know how T,P affect the solubility of both solids and gases in water apply the terms concentation, solute, solvent, molarity understand Beer's Law (A=abc) and its application to colorimetry (A=-logT)
DO	make solutions from a solid + water using a volumetric flask solve concentration problems involving mass, volume, and concentration (in molarity) solve dilution problems using c1V1=c2V2 use a colormieter to measure %T of solutions solve Beer's Law problems to find concentration of unknowns

TAKE-HOME ESSAY: Do you agree with Patricia Poore that "a major impediment to sound environmental policy is the general lack of scientific understanding among both the public and the legislature"? Support your position with two examples, at least one of which comes from the article "The Dose".
