Reaction Rates

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.
b. Students know how reaction rates depend on such factors as concentration, temperature,
and pressure.
c. Students know the role a catalyst plays in increasing the reaction rate.
d.* Students know the definition and role of activation energy in a chemical reaction.
