For exothermic reactions, ΔH is always negative, energy is considered a product, and energy is released in the reaction.

An exothermic reaction is one in which energy, usually in the form of heat, is released to the environment from the reaction. In other words, the final temperature of an exothermic reaction would always be more than the initial temperature.

This also means that heat energy is a product of exothermic reactions and this heat is released to the environment from the reaction.
