WebSep 12, 2024 · Key Facts. Endothermic and exothermic reactions are chemical reactions that absorb and release heat, respectively. A good example of an endothermic reaction is photosynthesis. Combustion is …
WebA change that releases heat is called an exothermic process. For example, the combustion reaction that occurs when using an oxyacetylene torch is an exothermic process—this process also releases energy in the form … WebAn exothermic reaction results in a negative enthalpy change, which we can see in the graph where the dip is. We can see it gained some energy, but then releases a lot more than it gained to the point where it is lower than where it originally was.. As it goes through the exothermic process, the system's overall potential energy declined ...
