Chemical equilibria, Le Chatelier's principle and Kc study guide

Study Guide: Chemical Equilibria

Key Concepts

• Dynamic Equilibrium: Understand the definition and characteristics of dynamic equilibrium in closed systems.
• Le Chatelier's Principle: Familiarize yourself with how changes in concentration, pressure, and temperature affect equilibrium positions.
• Catalysts: Recognize the role of catalysts in chemical reactions and their effect on equilibrium.

Kc Expressions

• Learn how to construct Kc expressions for various reactions, ensuring you account for the correct stoichiometry.
• Practice calculating Kc from given equilibrium concentrations and vice versa.

Units of Kc

• Be able to determine the units of Kc based on the reaction's stoichiometry.

Magnitude of Kc

• Interpret the significance of Kc values in terms of the position of equilibrium, understanding what large or small Kc values imply about the reaction's favorability.
