Chemical equilibrium is a balancing act-what happens when the balance is disturbed? In this activity-stations lab, students investigate various reaction conditions that may influence that balance. Four “mini-lab” activities are set up around the clas...

Our physical sense of equilibrium suggests a condition of equal balance-in the motion of a seesaw, the swing of a pendulum, the stretch of a spring. How does physical equilibrium translate to the properties of chemical equilibrium? In this comprehens...

From ozone depletion to the production of smog, important reactions that occur in the atmosphere involve equilibrium concentrations of gaseous reactants and products. Students, using microscale techniques, investigate how temperature and pressure aff...

What is equilibrium? What happens to the amounts of reactants and products when equilibrium is reached? What if more reactants or products are then added? Well, seeing is believing! In this cooperative classroom activity, student use plastic nickels ...

Equilibrium is a true chemical balancing act. What happens when the delicate balance is disturbed? In this classic chemistry experiment, students examine how concentration and temperature affect the sensitive “pink-and-blue” balance in the complex-io...
