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. Collision Theory: Definition & Significance
This lesson will define and explain collision theory and explore how it is related to chemical reactions and reaction rates. So if you've ever wondered how two particles combine to form a new product, read on!
5. 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.
6. 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.
7. Chemical Kinetics, Reaction Rate Constant & Equilibrium Constant
Are formulas, rate constants, and chemical reactions getting you down? Don't worry, this lesson will explain how reaction rate and equilibrium constants are related to chemical reactions.
