About This Chapter
Who's it for?
Anyone who needs help learning or mastering college-level general chemistry material will benefit from taking this course. There is no faster or easier way to learn college-level general chemistry. Among those who would benefit are:
- Students who have fallen behind in understanding the rate of a chemical reaction or working with the modifying factors
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning science (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about kinetics
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources
How it works:
- Find videos in our course that cover what you need to learn or review.
- Press play and watch the video lesson.
- Refer to the video transcripts to reinforce your learning.
- Test your understanding of each lesson with short quizzes.
- Verify you're ready by completing the Kinetics chapter exam.
Why it works:
- Study Efficiently: Skip what you know; review what you don't.
- Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
- Be Ready on Test Day: Use the Kinetics chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any kinetics question. They're here to help!

Students will review:
This chapter helps students review the concepts in a Kinetics unit of a standard college-level general chemistry course. Topics covered include:
- Rate constant and rate laws
- Rate of a chemical reaction
- Activity energy and catalysts
- Reaction mechanisms and the rate-determining step
- Factors that affect the rate of chemical reactions
1. Rate of a Chemical Reaction: Modifying Factors
Why are some reactions much faster than others? Is it possible to change how fast a reaction occurs? In this lesson, you will learn what the rate of a chemical reaction is. You will also discover how factors such as temperature, concentration, surface area, and catalysts impact reaction rates.
2. Rate Constant and Rate Laws
Learn what the rate law is and how the rate constant relates to it. Learn what reaction order is and how to determine reaction order when given experimental data containing concentration and reaction rate.
3. Rate of a Chemical Reaction: Effect of Temperature
Learn how temperature affects reaction rates. Discover the rate law as well as how the Arrhenius equation relates to the rate law and predicts the effect of temperature on the rate of reaction.
4. Activation Energy and Catalysts
Learn how to define activation energy and how it relates to a reaction's energy. Learn what an activated complex is and where it fits into an activation energy diagram. Discover how a catalyst works to change the activation energy of a reaction and what this means to metabolism in the body.
5. Reaction Mechanisms and The Rate Determining Step
This lesson explores what a reaction mechanism is and how it relates to the speed of a reaction. You'll discover how to pinpoint the rate-determining step and learn how to write a rate law based on the rate-determining step.
6. Second Order Integrated Rate Law
In this lesson, we will give the equation for the second order integrated rate law. We'll discuss its graph and then set up and solve a simple example problem.
