MIAMI-DADE COUNTY PUBLIC SCHOOLS Student BYOD Resource Page CHEMISTRY I HONORS TOPIC XIV: Reaction Rates Course Code: 200335001 Pacing Date Traditional 11 days Block ESSENTIAL CONTENT A. Develop the concept of Collision Theory 1. Develop the concept of how reactants must collide in the correct orientation and with sufficient energy to produceproducts 2. Develop the concept of Activation Energy OBJECTIVES Explain collision theory by relating chemical reactions to collisions between reacting particles. Explain the factors that affect reaction rates such as temperature, concentration, surface area, catalyst, and pressure Draw and label potential energy diagrams to show how B. Factors Affecting Reaction Rates energy changes as the reaction progresses 1. Explain how and why a catalyst affects reaction rates Find the difference in energy between reactants and 2. Explain how and why temperature affects reaction products (Δ H) and determine if the reaction is rates exothermic or endothermic 3. Explain how and why surface area affects reaction Find the catalyzed and uncatalyzed activation energy of rates a reaction using a potential energy diagram and 4. Explain how and why concentration affects reaction describe how a catalyst affects reaction rate. rates Recognize reactions that are reversible. 5. Explain how and why pressure affects reaction rates Explain the concept of dynamic equilibrium in terms of reversible processes occurring at the same rates. C. Energy Diagrams 1.
