Equilibrium: Chemical and Dynamic

1. Equilibrium: Chemical and Dynamic

Chemical equilibrium occurs when the rate of a forward chemical reaction is equal to the rate of reverse reaction while the concentrations of products and reactants remain unchanged. Learn about equilibrium constant, dynamic state, chemical equilibrium, and how chemists use equilibrium constant equations.

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

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

Le Chatelier's Principle refers to the process of disruption and the re-establishment of equilibrium. Learn about this principle, and understand how changes in concentration, temperature, and pressure affect equilibrium.

Equilibrium Constant (K) and Reaction Quotient (Q)

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

The equilibrium constant, K, is a number that expresses the ratio of products and reactants in a reaction once it reaches chemical equilibrium. Explore the state of equilibrium and the significance of chemical equilibrium and the reaction quotient (Q).

Using a RICE Table in Equilibrium Calculations

4. Using a RICE Table in Equilibrium Calculations

A RICE table is used to solve equilibrium calculations. Discover what a RICE table looks like, how it is used to solve for amounts of reactants, and how to use the RICE table to solve for Keq.

Rate of a Chemical Reaction: Modifying Factors

5. Rate of a Chemical Reaction: Modifying Factors

Reaction rate is defined as the change in concentration of reactants or products in a chemical reaction over a specific period of time. Learn about reaction rate, chemical reactions, and the factors that affect the rate of chemical reactions (temperature, concentration, surface area, & catalysts).

Rate Constant and Rate Laws

6. Rate Constant and Rate Laws

Rate law is defined as the relationship between the rate of reaction and the concentration of the reactants. Learn about rate law, rate constant, and how to use rate law equations to determine reaction order for one or two reactants.

Rate of a Chemical Reaction: Effect of Temperature

7. Rate of a Chemical Reaction: Effect of Temperature

The rate of a chemical reaction is affected by temperature. Explore this process, learn about the Arrhenius equation, review the exponential factor, and define frequency factor.

Activation Energy and Catalysts

8. Activation Energy and Catalysts

Activation energy refers to the minimal quantity of energy required for compounds to experience a chemical reaction. Learn about activation energy and how chemical reactions occur, understand activated complex and transition state, and explore the role of catalysts in the body.

Reaction Mechanisms and The Rate Determining Step

9. Reaction Mechanisms and The Rate Determining Step

A reaction mechanism refers to the steps that occur in a chemical reaction. Learn about reaction mechanisms, including intermediates, and understand the role of the rate-determining step, a step that is slower than the other steps and controls the reaction rate.

Biochemical Reactions: Synthesis and Decomposition

10. Biochemical Reactions: Synthesis and Decomposition

In biochemical reactions, substances react to one another to produce a product. Explore more about the different types of biochemical reactions, including synthesis reactions, decomposition reactions, and reversible reactions.
