REACTION RATES REVIEW
 Be able to define and/or describe the following terms:
reaction rate
endothermic reaction
collision theory
catalyst
effective collision (2 criteria for this)
concentration
activation energy
potential energy
exothermic reaction
 List and explain the factors that affect the rate of a chemical reaction
 Review the results of the chemistry in the kitchen lab. How did temperature and concentration
affect the reactions?
 Know all of the parts of a potential energy diagram. Be able to analyze a diagram for quantitative
data.

Label the following, and determine their quantitative measurements in kilojoules (kJ):
•
activation energy of the forward reaction
•
activation energy of the reverse reaction
•
how a catalyst affects the pathway
•
the energy of the products
•
the energy of the reactants
•
energy of the activated complex
•
the heat of reaction (ΔH)
•
is the forward reaction exothermic or endothermic? How do you know?
•
add the term “heat” in the correct position in the following chemical equation:
REACTANTS  PRODUCTS
