Equilibrium

Learn about the basics of chemical equilibrium, including how to write the expression for chemical equilibrium.

Learn what Le Chatelier's Principle is and how it can be applied to predict the effect of a change in conditions on chemical equilibrium.

Learn how to classify chemical reactions using kinetics. Identify and define zero, first, second, mixed, and higher order reactions.

Learn what catalysts are and how they affect the activation energy and reaction rate of a chemical reaction.

Several factors affect the rate at which chemical reactions proceed. Understanding these factors will help you predict the direction and speed of a chemical reaction.

The equilibrium constant is calculated from the expression for chemical equilibrium. Learn what the equilibrium constant, how to calculate the equilibrium constant and what it means if the equilibrium constant is very large or very small.

This example problem demonstrates how to find the equilibrium constant of a reaction from equilibrium concentrations of reactants and products.

This example problem demonstrates how to use the equilibrium constant of a reaction to determine equilibrium concentrations of reactants and products.

This example problem demonstrates how to find the equilibrium constant and pressure equilibrium constant of a gaseous reaction from the pressures of the gases.

This example problem demonstrates how to use the reaction quotient to predict the direction of a chemical reaction towards equilibrium.

This example problem demonstrates how to calculate the equilibrium concentrations from initial conditions and the reaction's equilibrium constant. This equilibrium constant example concerns a reaction with a "large" equilibrium constant.

This example problem demonstrates how to calculate the equilibrium concentrations from initial conditions and the reaction's equilibrium constant. This equilibrium constant example concerns a reaction with a "small" equilibrium constant.
