Which of the following is true regarding exothermic reactions?

Exothermic reactions are characterized by the release of energy, typically in the form of heat or light, during the process of the reaction. This release of energy occurs because the total energy of the products is lower than that of the reactants, meaning that energy is given off as the reaction proceeds. This release can often be felt as a temperature increase in the surroundings or can be observed through the emission of light. This fundamental aspect of exothermic reactions is a key concept in thermochemistry and is significant in many chemical processes, including combustion and respiration.

The other options describe misconceptions about exothermic reactions. For instance, stating that exothermic reactions absorb energy contradicts the very definition of what makes a reaction exothermic. Additionally, claiming that these reactions do not involve energy transfers overlooks the core concept of energy release, and suggesting that they occur only at high temperatures is inaccurate, as exothermic reactions can occur at a range of temperatures.
