Equilibrium

Physics stars design mobiles that demonstrate rotational equilibrium. They take measurements and solve related equations for force by graphing, substitution, or determinants. This is a well-developed lesson plan, complete with student...

Graphic organizers, photos, diagrams, and text bring the world of chemical reactions to life. By viewing this presentation, young chemists learn how to recognize when a chemical reaction has occurred, and how to balance chemical...

Sal introduces students to Hess's Law. The law states that the energy change of a process is independent of how we get from one state to another. He sets up a series of reactions, and solves them to illustrate the principles behind...

Why do reversible reactions just keep going and going? Savvy solution chemists learn how to influence reactants and products at equilibrium through a video lesson. Topics include the conditions that affect equilibrium, reaction rates,...

The breakdown of your breakfast and plants photosynthesizing all relate to the simple movement of electrons. Learn about the complex manner of redox reactions, where electrons move from one compound to another, changing and propelling...

Students determine an equilibrium constant using a spectrophotometer. In this equilibrium lesson plan, students calibrate a spectrophotometer with 5 solutions in order to prepare the spectrophotometer for the experiment. Students measure...

Don't throw your pupils' balance off when calculating equilibrium problems — teach them how to manage all that knowledge. Equilibrium calculations combine many concepts to answer a single question. Instructors explain four...

Explore the characteristics of a reaction in dynamic equilibrium. The 12th installment in a series of 35 video lessons discusses the concept of dynamic equilibrium. The video instructor uses animation to demonstrate the process.

Equilibrium reactions are able to reach a steady state of products and reactants, but what happens when this careful balance is disturbed? With the help of this instructional video, young chemists learn to apply Le Chatelier's...
