Summary:
- An exothermic reaction is a chemical reaction in which less energy is needed to break bonds in the reactants than is released when new bonds form in the products.
- During an exotherMIC reaction, energy is constantly given off, often in the form of heat.
- During combustion, a substance burns as it combines with oxygen, releasing energy in the forms of heat and light.
- If the energy produced in an Exothermic Reaction is released as heat, it results in a rise in temperature.
- As a result, the products are likely to be warmer than the reactions.
