activation energy.
An exothermic reaction is a type of chemical reaction where the energy of the products is less than the energy of the reactants. This means that energy is released during the reaction in the form of heat or light. Examples include combustion reactions and many neutralization reactions.
The amount of heat given off by the reaction
The difference in energy between the products and reactants of a chemical reaction determines if energy will be released or absorbed. If the products have lower energy than the reactants, energy will be released in the form of heat or light. If the products have higher energy, then energy will be absorbed.
The chemical energy in the reactants is almost equal to the chemical energy in the products
The energy change when reactants are converted to products in a chemical reaction is known as the enthalpy change (∆H). It represents the difference in energy between the products and reactants. Depending on whether energy is released or absorbed during the reaction, the ∆H value can be negative (exothermic) or positive (endothermic).
In a chemical reaction, the chemical energy of the reactants is typically higher than that of the products. This is because energy is needed to break the bonds in the reactants to form new bonds in the products. The difference between the energy of the reactants and the products is often released or absorbed as heat.
A chemical reaction whose reactants have less potential energy than the products would be called an endothermic reaction.

An exothermic reaction is a type of chemical reaction where the energy of the products is less than the energy of the reactants. This means that energy is released during the reaction in the form of heat or light. Examples include combustion reactions and many neutralization reactions.
This is called: Activation energy (abbrev. Ea)
reactants and products and bond energy creates a chemical reaction
The amount of heat given off by the reaction
Energy is released when a chemical reaction is exothermic, meaning that the products have less energy than the reactants. Energy is absorbed in an endothermic reaction, where the products have more energy than the reactants.
During a chemical reaction, energy is either absorbed or released. In an endothermic reaction, energy is absorbed to convert low-energy reactants into high-energy products. In an exothermic reaction, energy is released as high-energy reactants are transformed into low-energy products.
The difference in energy between the products and reactants of a chemical reaction determines if energy will be released or absorbed. If the products have lower energy than the reactants, energy will be released in the form of heat or light. If the products have higher energy, then energy will be absorbed.
A potential energy graph in chemistry shows the energy changes that occur during a chemical reaction. It reveals how the energy of the reactants compares to the energy of the products. The graph can indicate whether the reaction is exothermic (releasing energy) or endothermic (absorbing energy), and the overall energy difference between the reactants and products.
The chemical energy in the reactants is almost equal to the chemical energy in the products
