The word activation is interpreted as: activate huóhuà. 1. makes the chemical properties of molecules and atoms more active and energetic. 1. Because of the existence of adjacent groups, the molecule can participate in the reaction or increase the reactivity between the parts of the molecule. 2. Transforming a compound, such as a provitamin or an enzyme, into an active form or a different compound, especially into a substance with special biological activity. 3. To make (a substance) radioactive, fluorescent, photosensitive or photoconductive by treating it (such as by radiation or electric oscillation) or doping impurities. The part of speech is: verb. Pinyin is huóhuà. The phonetic notation is: ㄨㄛㄨㄚ. The structure is: living (left and right structure) (left and right structure).
What is the specific explanation of activation? We will introduce you through the following aspects:

The process of giving energy to a substance from the outside, transforming it from a low-energy reactant into a high-energy activated complex, and then releasing energy from the activated complex to form a product. Word translation English activation German activation _ French activation
Second, the network interpretation
Activation In a chemical reaction, in order to make a chemical reaction between reactants, their molecules and other particles must first collide with each other. Experiments have proved that countless collisions between molecules are mostly ineffective; Only the collision between a few molecules can trigger a chemical reaction. This kind of collision that can produce chemical reaction is called effective collision. Molecules that collide effectively are called activated molecules. Molecules have energy due to thermal motion. The average energy of all molecules is very low, and some molecules have high energy for various reasons. They are called active molecules. Therefore, the activation process is the process of adding catalyst in the chemical reaction, which increases the number of activated molecules and reduces the activation energy of the whole chemical reaction.
