With an overview of topics related to chemical energetics, this site provides a foundation to a study of thermodynamics and molecules as energy carriers and converters. Topics covered include how molecules take up thermal energy,...

This lab further analyzes the results of the experiments carried out in Chemical Kinetics 1. In addition, you will carry out experiments to determine the temperature dependence of the reaction rate constant. Requires Java plug-in.

Discusses and explores the impact of random pressure errors on the equilibrium constant in a chemical reaction. Requires Java.

This diagram illustrates a chemical reaction forming a precipitate.

[Free Registration/Login may be required to access all resource tools.] Students determine the temperature at which a reversible reaction will achieve equilibrium by using the Gibbs free energy equation, and then describe the...

Reversible reactions, equilibrium, and the equilibrium constant K. Learn how to calculate K, and how to use K to determine if a reaction strongly favors products or reactants at equilibrium.

Definition of Arrhenius acids and bases, and Arrhenius acid-base reactions.

Svante Arrhenius was born in Vik, Sweden, and became the first native of that country to win the Nobel Prize. The award for chemistry was bestowed to him in honor of his theory of electrolytic dissociation. Arrhenius also developed the...

A page describing how Mole Day is celebrated at the Massachusetts Academy for Mathematics and Science. Some ideas for celebrations can be found here.

See examples of the three types of gas stoichiometry problems: mole-volume, mass-volume, and volume-volume.

Though it has increased food supply worldwide, the Haber process has taken an unforeseen toll on the environment. Daniel D. Dulek delves into the chemistry and consequences of this. [5:19]
