6.1 Reaction Enthalpy and Bond Dissociation Energy | Organic Chemistry

Chad reviews reaction coordinate diagrams contrasting endothermic and exothermic reactions. He explains how to identify Delta H, the activation energy, and the transition state on a reaction coordinate diagram. He then introduces and defines bond dissociation energy (aka bond enthalpy) and covers trends for them. Chad concludes the lesson by working an example to show how bond dissociation energies can be used to calculate an approximate value for Delta H.
