In every-day language, synonyms of “equilibrium” include balance, symmetry, parity, equality, and stability. These every-day words may suggest that “things have stopped – and activity is static.” While it is true the expression equilibrium in chemistry applies to the absence of changes in concentrations of reactants or products – at the molecular level, things are dynamic, not static. Here, students are introduced to the law of chemical equilibrium (once called “the law of mass action”). Changes in volume and/or pressure are examined for their respective impact on equilibrium. Students further familiarize themselves with concepts dealing with solubility and usages of the equilibrium constant (denoted as “K”).
