Energetics (also called energy economics) is the study of energy under transformation because energy flows at all scales, from the quantum level to the biosphere and.
Exothermic and endothermic reactions when a chemical reaction occurs, energy is transferred to, or from, the surroundings - and there is often a temperature change. Chemists are often interested in how fast a reaction will occur, and what we can do to control the rate the study of reaction rates is called kinetics, and we will learn about average reaction rate, rate laws, the arrhenius equation, reaction mechanisms, catalysts, and spectrophotometry. Enthalpy change is the term used to describe the energy exchange that takes place with the surroundings at a constant a-level » chemistry » chemical energetics.
