Give your chemistry students a focused look at le châtelier’s principle with ninety questions built for real classroom use, whether you are starting a new unit or reviewing before a test.

Among the ninety questions, students will see prompts such as "In an equilibrium of A ⇌ B, if B is removed, what will happen?", "In the reaction CO(g) + 2H₂(g) ⇌ CH₃OH(g), what effect does decreasing the pressure have?", and "What is the effect of removing a reactant in a reaction at equilibrium?"

What's Inside?

• 30 Multiple Choice questions as a separate print ready PDF worksheet
• 30 True or False questions as a separate print ready PDF worksheet
• 30 Short Answer questions as a separate print ready PDF worksheet
• Includes Answer Key with Explanations for all 90 questions
• 6 print ready PDF files, 27 pages in total

All three worksheets cover the same topic in different question styles. That means you can use one as a pretest, another for practice or homework, and the third as a follow up quiz, without students ever seeing the same question twice.
