Curated OER
Le Chatelier's Principle
In this chemical reactions activity, students apply the Le Chatelier's principle to determine the equilibrium shift in the reaction based on specific changes to the system. This activity has 2 short answer questions and 2 problems to solve.
Curated OER
Le Chatelier's Principle
In this chemical reaction learning exercise, students apply Le Chatelier's Principle to explain how the given changes in reaction conditions will affect the position of equilibrium. This learning exercise has 6 problems to solve.

Reaction Mechanisms
In this reactions worksheet, students give the equation for the overall reaction, identifying the catalyst in the equation. Students create graphs and write out the rate determining step. This worksheet has 4 graphs, 2 short answers, and...
Curated OER
Equilibrium
For this equilibrium worksheet, students predict the concentrations of solutions at equilibrium and apply Le Chatelier's principle to systems at equilibrium. This worksheet has 15 multiple choice questions.
Curated OER
Equilibrium Problems
In this equilibrium worksheet, students determine what effect a catalyst has on the rate of a reaction and the activation energy. Students explore how the equilibrium shifts when different stresses are added to a compound. This worksheet...
Curated OER
Chemistry
In this chemistry worksheet, students describe an atom, its parts, the charges of these parts, and atoms life functions. Then they explain what the octet rule states for the placements of electrons around the nucleus of an atom. Students...
