SC5. Students will understand that the rate at which a chenical reaction occurs can be affected by changing
concentration, ten-verature, or pressure and the addition of a catalyst.
a. Demonstrate the effects of changing concentmtion, temperature, and pressure on chernical reactions.
b. Investigate the effects of a catalyst on chernical reactions and apply it to everyday examples.
c. Explain the role of activation energy and degree of mndonmess in chernical reactions.
College Board AP Chemistry Topic Outline:
Ill. Reactions
D. Kinetics
1. Concept of rate of reaction
2. Use of experimental data and graphical analysis to determine reactant order, rate constants and reaction rate
laws
3. Effect of temperature change on rates
4. Energy of activation; the role of catalysts
5. The relationship between the rate-determining step and a mechanism
Enduring Understandings: Students will understand that... Essential Questions:
• concentration, physical states of reactants,
temperature, and catalysts affect the rate of a reaction.
• there is a relationship that exists between the
disappearance of reactants and the appearance of
roducts.
Knowledge: Students will know...
-how to calculate the rate of a reaction based on
concentration.
• What factors affect the rate of a reaction?
• What are reaction mechanisms?
• How do catalysts speed up the rate of a
reaction ?
Skills: Students will be able to...
calculate the rate of a reaction.
-the step- by-step molecular pathways leading from reactants
to roducts.

QI_JIZ: Chemical Kinetics quiz
HOIvfEWORK: Read the lab for tomorrow.
LAB: Students will complete the iodine clock reaction to study chemical
kinetics. Students will vary the concentration of the reactants and
temperature to observe how this changes the reaction rate.
