In an exothermic reaction, how is temperature treated?

In an exothermic reaction, temperature is treated as a product because the reaction releases energy in the form of heat to the surrounding environment. This release of heat results in an increase in temperature of the surroundings, indicating that energy has been produced as a result of the reaction.

In chemical equations that represent exothermic reactions, heat can be included as a product. For example, in the combustion of hydrocarbons, the heat released can be expressed in the balanced chemical equation, illustrating that the energy produced is part of the overall output of the reaction.

This is distinct from how temperature is treated in endothermic reactions, where heat is absorbed and thus can be considered as a reactant. The identification of temperature as a product in exothermic reactions highlights the thermodynamic nature of these processes, wherein energy transformation is a critical aspect of the reaction mechanism.
