Le Chatelier's Principle
Equilibrium reactions are able to reach a steady state of products and reactants, but what happens when this careful balance is disturbed? With the help of this instructional video, young chemists learn to apply Le Chatelier's...

What Triggers a Chemical Reaction?
Chemical reactions are happening all around us every second of every day, but what exactly causes these changes to occur? Using easy-to-understand analogies, this video explains how the concepts of enthalpy and entropy determine the ways...

Entropy & Free Energy
An understanding of chemical reactions really boils down to two concepts: entropy and enthalpy. Follow along with this instructional video as it explains how these two principles are used to calculate Gibbs free-energy which...
