Determining the Equilibrium Constant (and Temperature’s Effect) with Beer’s Law

Targets Grades: 10-14
Accommodates 24 Students Working in Groups of 2

Loaded with important concepts and techniques for the AP chemistry student; determine the equilibrium constant using Le Chatelier’s principle and Beer’s Law (using spectrophotometry) to determine equilibrium concentrations of reactants and products. Addresses the inquiry question: What is the effect of temperature on the equilibrium constant? Minimal prep time; easily adapted
to three shorter lab periods. State of the Art instructor’s manual features background material, easy to follow stepwise protocols, assessment questions, sample data, modeled calculations, and an answer key. Additional equipment required: spectrophotometers, glassware, and thermometers. Meets AP Science Practices 2 & 7.
