<u>Answer:
</u>
A reaction in which the reactants have more energy than the products is always an Endothermic reaction.
<u>Explanation:</u>
The word "exothermic" means "turning out".In endothemic reaction, less amount of energy is sufficient to break the bonds that exist between the reactants when compared to the amount of energy that is formed when new bonds are created.
The chemical energy that is stored within a product is nothing but its potential energy that can later be released. An example of an endothermic reaction is the burning of wood. when you burn wood, you can see that it releases energy in the form of heat and this warms up the surrounding environment.
