WebSep 12, 2024 · As I understand the chemistry though, adding heat to an exothermic reaction should slow the reaction and effectively take longer for the joint to cure. Higher temperature means higher reaction speed, due to higher molecular kinetic energy. What changes for exothermic vs. endothermic reactions is their equilibrium point, not their speed. WebJan 14, 2024 · An exothermic reaction is a chemical reaction that releases heat and has a negative enthalpy (-ΔH) and positive entropy (+ΔS).. These reactions are energetically …

WebIf a reaction is endothermic, where heat is absorbed as the reaction progresses from reactants to products, then increasing the temperature will increase the equilibrium … WebFeb 23, 2024 · This chemical reaction of iron and oxygen, also, creates a new substance, iron oxide (FeO2). Iron oxide is heavier than iron, making the resulting product heavier than the original steel wool. This experiment is an example of an exothermic reaction, a chemical reaction that releases energy in the form of heat. Once the steel wool has burned, it ...
