An exothermic reaction .
In an endothermic reaction, the energy of the products is
the energy of the reactants.
Activation energy is
the potential energy of the products.

An exothermic reaction Produces energy

In an endothermic reaction, the energy of the products is more than the energy of the reactants.  and  Activation energy is always greater than the potential energy of the products

An endothermic reaction is a reaction which requires an external source of energy before the reaction will take place ( i.e. endothermic reaction absorbs energy in the form of heat from its surrounding ) while an exothermic reaction releases energy in the form of heat into the environment.

Activation energy is amount of energy required to start a reaction since an endothermic reaction absorbs energy from its environment to kick off its reaction, its activation energy is always higher than the potential energy of its products.

Hence we can conclude that An exothermic reaction Produces energy In an endothermic reaction, the energy of the products is more than the energy of the reactants.   and Activation energy is always greater than the potential energy of the products.
