This page looks at Le Chatelier's Principle and explains how to apply it to reactions in a state of dynamic equilibrium. It covers changes to the position of equilibrium if you change concentration, pressure or temperature. It also...

Students observe the effects of temperature change on the color of nitrogen dioxide and dinitrogen tetroxide by manipulating glass tubes containing the gases at equilibrium. Then, they write a balanced equation for the reaction and...

In this activity, students safely explore the equilibrium reaction of the cobalt chloride reaction.

[Free Registration/Login Required] Explore Le Chatelier's Principle by changing the volume, pressure, and temperature in a bottle of soda. Try carbonating the soda to see how adding a reactant affects the chemical equilibrium.

Through informational text, interactive practice problems, virtual simulations, and video clips, students learn about reaction rates and equilibrium.

This lesson will provide examples of how to identify an equilibrium shift due to a change in concentration of either reactants or products.
