An exothermic reaction is one that, through either light or heat, releases energy.
It can be expressed simply as:
reactants --> products + energy
The potential energy at the end of the reaction is always lower than at the beginning of the reaction.
An endothermic reaction is a reaction that absorbs energy from its surroundings.
It is essentially reactants + energy ----> products.
Hope this helps,
