Equilibrium: Chemical and Dynamic

1. Equilibrium: Chemical and Dynamic

Learn the definition of chemical equilibrium and how it is dynamic. Discover what the equilibrium constant is and how it shows whether the reaction favors the reactants or products. Learn how chemists designate equilibrium in an equation and how they show the difference in reaction rate.

LeChatelier's Principle: Disruption and Re-Establishment of Equilibrium

2. LeChatelier's Principle: Disruption and Re-Establishment of Equilibrium

Learn how Le Chatelier's Principle describes the disruption and re-establishment of equilibrium. Learn to explain the factors that disrupt equilibrium, such as concentration, temperature, and pressure. Learn how each of these factors affects a system in equilibrium.

Equilibrium Constant (K) and Reaction Quotient (Q)

3. Equilibrium Constant (K) and Reaction Quotient (Q)

In this lesson, we will first define and explain the notion of a chemical equilibrium. Then, you'll learn about the equilibrium constant and reaction quotient. Finally, we'll round off the lesson with a couple of examples to solidify what you've learned!

Using a RICE Table in Equilibrium Calculations

4. Using a RICE Table in Equilibrium Calculations

Learn what the RICE table is and how to fill in the table with the reaction, initial concentration, change in concentration and amount of product and reactants at equilibrium. Learn how to use the RICE table to calculate the concentrations and amounts and the equilibrium constant of equations at equilibrium.

Rate of a Chemical Reaction: Modifying Factors

5. 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 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.

Rate of a Chemical Reaction: Effect of Temperature

7. 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.

Activation Energy and Catalysts

8. 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.

Reaction Mechanisms and The Rate Determining Step

9. 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.

Biochemical Reactions: Synthesis and Decomposition

10. Biochemical Reactions: Synthesis and Decomposition

Did you know that there are thousands of chemical reactions going on in your body every day? In this lesson, you will learn about three types of biochemical reactions: synthesis reactions, decomposition reactions and reversible reactions.
