Kinetics & Equilibrium

14 min read

Collision theory, activation energy, catalysts and the Maxwell–Boltzmann distribution, plus dynamic equilibrium and Le Chatelier's principle.

This chapter explains how fast reactions go and how far they proceed.

Collision theory

A reaction occurs when particles collide with enough energy (the activation energy, EaE_aEa​) and the correct orientation. Rate increases with concentration/pressure, temperature, surface area and a catalyst.
