Reaction Mechanisms and The Rate Determining Step

1. 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.

Activation Energy and Catalysts

2. 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.

Changes in Heat and Energy Diagrams

3. Changes in Heat and Energy Diagrams

Did you know that temperature and heat are not the same thing? Did you know that the temperature of water doesn't change when it boils? This lesson describes the relationship between heat and temperature. Diagrams are used to illustrate the relationship between heat and temperature during phase changes.

Rate of a Chemical Reaction: Modifying Factors

4. 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.

Rate of a Chemical Reaction: Effect of Temperature

5. 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.

Rate Constant and Rate Laws

6. 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.
