Exothermic sublimation
WebOct 19, 2024 · In contrast, an exothermic process is one in which heat is released as the reaction occurs. For example, when wood burns, it undergoes an exothermic reaction, … WebAn exothermic reaction is a chemical reaction that delivers energy through light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy. Exothermic Reaction means "Exo" meaning releases and "thermic" means heat. In an exothermic reaction, by definition, the enthalpy change has a ...
