Questions:
1. What is the general form of a chemical reaction equation?
2. Where is the chemical energy in a compound found?
3. Draw a reaction energy diagram for an endothermic and exothermic reaction. Label the
position of the reactants, products and energy barrier.
4. For the reactions in #3, write out a general chemical equation that includes energy.
5. How does concentration, temperature and particle size affect the rate of a reaction?
6. How would a catalyst change the reaction energy diagrams you drew in question #3?
7. What are the four types of reactions that we discussed in class and how can each type be
identified?
8. How is a solution prepared?
9. How can a saturated and an unsaturated solution be distinguished?
10. How does temperature affect the dissolution rate of solid, liquid and gaseous solutes?
11. What happens to the freezing and boiling point of a solvent when a solute is dissolved in it?
12. What is true about temperature during a phase change?
13. Sketch a heating curve for a substance that melts at -20C and boils at 50C. Label the phases
that are present at each interval.
14. How are volume and shape described for solids, liquids and gases in terms of the particles in
them?
