How the exothermic and endothermic reaction is produced? when?
Answer:
Reactions consuming energy are called endothemic reactions.
Reactions releasing energy are called exothermic reactions.

exothermic releases energy to the surrounding environment throught the products and endothermic adsorbs energy from the environment in order for the reaction to take place.if u need to know more, email/im me.
in order for a compound(or element) to react it needs to have energy >= its activation energy.so it will consume energy,mostly in the form of heat.now after reacting the products will give out some energy.
if the total energy given out by the products is greater then the total energy absorbed by the reactants,then we get energy liberated in the form of heat.this is an exothermic reaction.
if the total energy absorbed by the reactants is > than the total energy liberated by the products the reaction is endothermic.
Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously. One example would be fire. There are other chemical reactions that must absorb energy in order to proceed. These are endothermic reactions. Endothermic reactions cannot occur spontaneously. Work must be done in order to get these reactions to occur. Photosynthesis is an example of an endothermic chemical reaction. In this process, plants use the energy from the sun to convert carbon dioxide and water into glucose and oxygen. Hope this helps you out kid.
The enthalpy of reaction (delta H) is defined as the enthalpy difference between the product(s) and reactant(s) of a reaction. In general, an exothermic reaction is one where the bonds formed in the product are stronger than that of the reactant. For example, a pi bond is weaker than a sigma bond. So if there are pi bonds in the reactant that convert into sigma bonds in the product, this may be an exothermic reaction. The opposite is true for endothermic reactions. Please note that exothermic/endothermic are terms that refer to enthalpy, and as a result, bonding. The terms exergonic/endergonic refer to the free energy of the reaction (delta G).
