Equilibrium Systems

Would you believe that your digestive system stretches to five times your height?! Help your pupils to understand this relationship as they work through the laboratory exercise. The first instructional activity of a 12-part series is a...

The reaction for hydrogen and nitrogen combining to form ammonia is provided at the top of this sheet, and then five sets of different conditions require your class to calculate the direction of shift and to state which is at...

A one-page instructional activity asks learners to explain what happens in different endothermic or exothermic reactions. To complete this, they must have a full grasp on LeChatelier's Principle and the workings of equilibrium constants....

Here is an excellent teaching tool for your advanced chemistry scholars. This handout explains chemical equilibrium, the equilibrium quotient, and the reaction quotient. Then it provides sample calculations for your class to try....

These two pages give your advanced chemistry class an adequate homework worksheet when studying chemical equilibrium. Reaction quotients are calculated, directions for system shift are predicted, diagrams are drawn. This gives learners...

The equilibrium constant does not change — as long as the temperature remains unchanged. Here's presentation that briefly reviews equilibrium constants  before working through four practice problems, including three calculating the Keq...

Time to shake up the status quo with a presentation that describes Le Chatlier's Principle and has pupils examine situations in which equilibrium is upset. Four examples show different stresses to the reaction and the resulting shift. 

Struggling your way through equilibrium systems? You—and your class—will think ICE is nice! Discover time-saving ways to solve equilibrium constant problems through a video from the JFR Science playlist. The narrator maps out the ICE...

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

By watching this droll and delightful animation, physical scientists consider what happens when molecules collide. In this film, however, parodic people bump into each other, exchanging limbs in the process, just as molecules might trade...
