$PV = nRT$, derived using Boyle’s Law, Charles’s Law, and Avogadro’s Law.

Le Chatelier’s Principle

A principle used to predict the effect of a change in conditions (concentration, pressure, temperature) on a chemical equilibrium.

Activation Energy

The minimum energy required for a chemical reaction to occur.
