This resource turns catalysts and equilibrium into a complete, ready to use review for Grade 9-12 chemistry, covering the same NGSS standard from three different angles.

Among the ninety questions, students will see prompts such as "Which of the following correctly describes the energy profile of a catalyzed reaction?", "How does a catalyst affect the activation energy of a reaction?", and "Why is a catalyst not consumed in a reaction?"

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.

Ways to Use This Resource

• No prep cover lesson for a substitute teacher
• First look diagnostic to plan your unit
• Self checking practice, since every answer key includes explanations
• Bell ringers and warm ups during the unit
• Review station before a lab or quiz

This set is part of a complete NGSS aligned chemistry unit. The unit also covers What Is Chemical Equilibrium, Forward and Reverse Rates, Le Châtelier’s Principle, Effect of Temperature, Effect of Pressure, and Effect of Concentration, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.

Suitable for Grade 9-12 chemistry classes, and for NGSS aligned review at any point in the school year. This set is aligned to NGSS standard HS-PS1-6.
