Reaction Rates
- 8. Chemical reaction rates depend on factors that influence the frequency of collision of reactant molecules. As a basis for understanding this concept:
- a. Students know the rate of reaction is the decrease in concentration of reactants or the increase in concentration of products with time. Ch. 17.1
- b. Students know how reaction rates depend on such factors as concentration, temperature, and pressure. Ch. 17.2
- c. Students know the role a catalyst plays in increasing the reaction rate. Ch. 17.2
- d.* Students know the definition and role of activation energy in a chemical reaction. Ch. 17.2
