An exergonic reaction is activation energy (or energy of activation).
An endergonic reaction is essentially the opposite of an exergonic reaction.

A catalyst can speed up the rate of a given chemical reaction by lowering the activation energy required for the reaction to occur. However, the catalyst does not change the total free energy from reactants to products.
The activation energy of ethyl acetate, which is the minimum energy required for a chemical reaction to occur, is specific to the reaction in question. Different reactions involving ethyl acetate will have different activation energies.
Endothermic
Geothermal energy is the type of energy that comes from the heat that is within the earth. Chemical energy on the other hand refers to the potential energy of a chemical substance to undergo a chemical reaction.
For most chemical reactions, energy is required to supply an "activation energy" required before reaction.
Energy that starts a chemical reaction is called activation energy
The energy necessary to initiate a chemical reaction is called "activation energy."
Activation energy in chemistry is the amount of energy required to start a reaction. For every chemical reaction, a certain amount of energy is required to start it
Exothermic reactions
they reduce the activation energy required for the reaction to occur
The presence of a catalyst in a reaction will lower the activation energy required to complete the reaction. The catalyst is not used up in the reaction, it is just there to speed it up.
All chemical reactions that release energy in the form of heat are called exothermic reactions.
The energy required is called the activation energy. The minimum amount of energy needed to start a chemical reaction is given by the formula Ea=-RT*ln(k/A). R is the universal gas constant, T is temperature in Kelvin, k is the reaction rate coefficient and A is the frequency factor.
it is not a chemical reaction. It is a nuclear reaction and it is called fusion.
Endothermic reactions.Endo- means 'inside' which is where the energy ends up.Exothermic reactions give off energy. Exo- means 'outside'. Think that a spider sheds an 'exo'skeleton, or a skin on the outside.
