Reaction rates

Introduction to kinetics

Kinetics, activation energy, activated complex and catalysts.

Reactions in equilibrium

Equilibrium reactions and constants.

Mini-video on ion size

Correcting a mistake and learning a bit about ion size

Keq intuition (mathy and not necessary to progress)

A probabilistic look at how molecules react to develop the intuition behind the equilibrium constant formula.

Keq derivation intuition (can skip; bit mathy)

A more concrete attempt at showing how the probabilities of molecules reacting is related to their concentration.

Heterogeneous equilibrium

Ignoring the solution or the solid state molecules when calculating the equilibrium constant.

Le Chatelier's principle

Le Chatelier's Principle regarding the "stressing" of reactions in equilibrium
