The general term for a chemical reaction that releases heat is an exothermic reaction.
An exothermic reaction is a chemical reaction that releases energy in the form of light or heat. It is the opposite of an endothermic reaction
Exothermic reactions
Endothermic reaction.
The term for releasing energy is ''Flagellation ''
The energy required to start a chemical reaction is called activation energy. It is the minimum amount of energy needed to initiate a reaction by breaking the chemical bonds of the reactants. This energy barrier must be overcome for the reaction to proceed.
An exergonic reaction is activation energy (or energy of activation). An endergonic reaction is essentially the opposite of an exergonic reaction.
A reaction releasing energy is called an exergonic reaction, so the opposite of the would be a reaction that needs energy to take place, called an endergonic reaction. These are also known as exothermic and endothermic reactions.
The energy needed to kick start a reaction is called activation energy. It is the minimum amount of energy required for a chemical reaction to occur. It is usually provided in the form of heat or light energy.
An Endothermic reaction. If you touch the reaction vessel it will feel cool/cold, as it is taking in heat energy. By contract an Exothermic reaction is one that gives out heat. If you touch the reaction vessel it will feel warm/hot as it is liberating heat energy.
The energy needed to start a chemical reaction is called the activation energy :)
An endothermic reaction is one in which heat energy is absorbed from the surroundings. In these reactions, the products have more energy than the reactants. Examples include photosynthesis and the melting of ice.
It's called the activation energy, depends on the reaction itself
