Help your students build real understanding of factors affecting rate through ninety questions that move from basic recognition to genuine reasoning about chemistry concepts.
Among the ninety questions, students will see prompts such as "Which of the following statements about catalysts is true?", "What is the effect of a catalyst on a chemical reaction?", and "How does increasing temperature generally affect reaction rates?"
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.
This set is part of a complete NGSS aligned chemistry unit. The unit also covers Reaction Rate Fundamentals, Temperature and Rate, Concentration and Rate, Surface Area Effects, Catalyst Effects, and Reaction Rate Lab Simulations, 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-PS1-5.
