How do you look at the reaction? Is it heat or heat?
There were several ways to determine whether the reaction was an exhalation or an absorption: 1. According to the energy relationship between the reagent and the product, if the total energy of the reagent is higher than the total energy of the product, the reaction is an exothermic reaction; if the total energy of the reagent is lower than the total energy of the product, the reaction is an xenothermic reaction. 2. According to the bond energy, it could be judged that the total bond energy of the reagent minus the total bond energy of the product. If the total bond energy of the reagent was greater than the total bond energy of the product, then the reaction was an heat absorbing reaction. If the total bond energy of the reagent was less than the total bond energy of the product, then the reaction was an heat absorbing reaction. 3. According to the basic types of chemical reactions, the reactions of acid and base, most of the displacement reactions, and most of the chemical combination reactions were all exothermic reactions. Most of the decomposition reactions were also the thermal reactions. The reactions of salt decomposition and dissolution were also the thermal reactions. However, this method of judgment could not be absolute. For example, the decomposition of kClO4 to produce kCl4 and oxygen was an geothermal reaction, and the transformation of lead to diamond under high pressure was an geothermal reaction (the opposite was true under normal pressure). 4. According to whether the reaction process required continuous external force, most of the exothermic reactions could be carried out spontaneously without continuous external force (such as light, electricity, etc.), but there were also exothermic reactions that required ignition or heating to occur (such as the reaction of hydrogen and oxygen to form water). There were also situations where the reaction could be carried out spontaneously without continuous external force, such as the reaction of lithium bis (bis). However, it was not possible to determine whether the reaction was an exhalation or an absorption simply based on whether an external force was needed. 5. According to the stability of the substance in the reaction, the reaction of forming an unstable substance from a stable substance was an alcoholic reaction, and vice versa. In addition, it was important to note that the dilute of concentrated sulfuric acid, the dissolution of the solid in water, and the heat absorption of the solid in water were not chemical reactions, nor were they in the scope of the heat absorption reaction or the heat release reaction.
