Examples are numerous: combustion, the thermite reaction, combining strong acids and bases, polymerizations. As an example in everyday life, hand warmers make use of the oxidation of iron to achieve an exothermic reaction: 4Fe + 3O2 → 2Fe2O3 ΔH⚬ = - 1648 kJ/mol A particularly important class of exothermic … 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 • Chemical thermodynamics • Differential scanning calorimetry • Endergonic • Exergonic • Endergonic 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 WebWhen chemicals react with each other they often give out heat during the reaction. This is known as an exotherm and it is something that is often witnessed when mixing …
