Chemical reaction that releases energy as light or heat The thermitereaction is famously exothermic. The reduction of iron(III) oxide by aluminiumreleases sufficient heat to yield molten iron. In thermochemistry, an exothermic reactionis a "reaction for which the overall standard enthalpy changeΔH⚬ is negative." See more In thermochemistry, an exothermic reaction is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative." Exothermic reactions usually release heat. The term is often confused with exergonic reaction, … See more The enthalpy of a chemical system is essentially its energy. The enthalpy change ΔH for a reaction is equal to the heat q transferred out of (or into) a closed system at constant pressure without in- or output of electrical energy. Heat production or … See more Examples are numerous: combustion, the thermite reaction, combining strong acids and bases, polymerizations.
