Unit 5: Kinetics

Students will develop an understanding of the rates at which chemical changes occur and the factors that influence the rates. Those factors include the concentration or reactants, temperature, catalysts, and other environmental factors. Overarching topics throughout the unit include:
- Some reactions happen quickly, while others happen more slowly and depend on reactant concentrations and temperature.
- There is a relationship between the speed of a reaction and the collision frequency of particle collisions.
- Many chemical reactions occur through a series of elementary reactions. These elementary reactions when combined form a chemical equation.
- The speed at which a reaction occurs can be influenced by a catalyst.

- Describe the components of and quantitative information from models and representations that illustrate both particulate-level and macroscopic-level properties.
- Identify an appropriate theory, definition ,or mathematical relationship to solve a problem.
- Explain the relationship between variables within an equation when one variable changes.
- Determine a balanced chemical equation for a given chemical phenomenon.
