Activity 1.1: An Introduction to Equilibrium Systems
Time: 10.0 hours
Description
This activity introduces students to the concept of dynamic equilibrium. They carry out an experiment to
determine the equilibrium constant for a system, followed by solving equilibrium problems involving
concentrations of reactants and products and K eq . There is an opportunity to incorporate the use of
available technology, e.g., graphing calculators and spectrophotometers. Students develop an
understanding of Le Chatelier’s principle and use it to predict the direction in which a system at
equilibrium will shift when volume, pressure, concentration, or temperature is changed, and to
investigate how it may be applied to optimize the production of industrial chemicals. Students review the
expectations for senior formal laboratory writing, in preparation for the End-of-Unit and Final
Performance Task.
