Chem1 Virtual Textbook - Free energy: the Gibbs function

Clear, comprehensive discussion of a difficult though important topic.

HyperPhysics - Gibbs Free Energy

Purdue University - Gibbs Free Energy

Excellent detailed treatment. Highly recommended. Try to bring everything you know about internal energy change, enthalpy change, and entropy change to the table. It is not about solving math problems. Try to understand what drives change in the world.

Chem1 Virtual Textbook - Some applications of entropy and free energy - Extraction of metals from their oxides

Interesting illustration of the application of the concept of Gibbs Free Energy to the process of smelting metal ores.

HyperPhysics - Hydrogen Fuel Cell
