What is endothermic reaction?

What Does endothermic reaction Mean

The nuclear reactions are those processes that lead to the combination or modification of atomic nuclei. When these nuclei combine or fragment, the release or absorption of particles and energy occurs .

If the nuclear reaction releases energy in the form of heat or light, the process is called an exothermic reaction . In contrast, when the reaction involves the absorption of energy , it is known as an endothermic reaction .
Endothermic reactions, therefore, are all chemical reactions in which energy is absorbed . It should be noted that, as a result of the reaction, the energy of the product is higher than the energy of the reactants.

In addition to all the above, we can determine that a clear example of an endothermic reaction is the production of what is known as Ozone. However, we cannot ignore either that, in the same way, it is the process of the so-called photosynthesis. In this, what happens is that the plants take the energy that the sun gives off to immediately transform what is water and carbon dioxide into oxygen and sugar.
In the same way, it is also established that the dissolution of ammonium nitrate in water, the obtaining of hydrogen, the cooling of the water and even the melting of the ice are endothermic reactions.
The endothermic reaction involves an increase in enthalpy . This concept refers to a magnitude whose variation reveals the level of energy that a thermodynamic system exchanges with the environment .
The ultraviolet rays that come from the sun, for example, generate an endothermic reaction in the upper layers of the atmosphere that leads to the generation of ozone . Another endothermic reaction occurs when iron reacts with sulfur and iron sulfide is produced .
In endothermic reactions, in short, the elements absorb energy from the system so that the nuclear reaction can take place. This means that, by taking thermal energy (heat), the reaction in question is produced or accelerated.
Just the opposite occurs with exothermic reactions that, during their development, release energy (as when a person lights a fire and produces fire, releasing heat).
Likewise, it is worth knowing other data of interest about the aforementioned reactions, among which we can highlight the following:

-Another of the examples thereof is the obtaining of chromium oxide from what is ammonium dichromate.

- It should not be overlooked either that an endothermic reaction between two solid type compounds is the one that occurs, for example, when the mixture of ammonium nitrate and barium hydroxide is undertaken.

-In these endothermic reactions, different types of energy can be used, although the most common is usually the calorific class. However, in the same way, you can proceed to make use of chemistry, light or electrical. Everything will depend on the results that are expected to be obtained and, above all, on the elements with which it is going to work.
