This study guide covers energy in reactions, focusing on elementary reactions, endothermic vs. exothermic reactions (illustrated with potential energy diagrams), and the progress of a reaction (reactants, activated complex, products). It also explains activation energy (Ea), its relationship to reaction rate, and the Arrhenius equation. Finally, it provides practice questions and exam tips.
