Exothermic and Endothermic Reactions
Most chemical reactions give out heat energy as they take place, so the products have less
energy (and so are more stable) than the reactants. These are exothermic reactions.

The Equilibrium Law
Le Chateliers principle gives us an idea of the direction of change, but, where concentrations
are involved, we can calculate precisely what happens using the equilibrium law.
