All chemical reactions release energy when they proceed
Chemical reactions involve the breaking and formation of chemical bonds, resulting in a change in chemical energy. Some chemical reactions release more energy than they use, which are known as exergonic reactions, while others absorb more energy than they use, which are known as endergonic reactions. However, it is important to note that not all chemical reactions release energy as they proceed, nor do all of them absorb energy.
For instance, the process of rusting and burning release energy and are exergonic reactions. On the other hand, some chemical reactions absorb energy rather than releasing it, such as the reaction between baking soda and vinegar, where energy is required to break the bonds in the reactants before new bonds can be formed. This endergonic reaction results in a decrease in the temperature of the surrounding environment.
Therefore, it is important to consider both exergonic and endergonic reactions when analyzing the energy changes in a chemical reaction. The study of energy changes in chemical reactions is crucial in fields such as chemistry, biology, and materials science, as it can provide insights into the behavior and properties of molecules and materials.
