WebExothermic reactions are chemical reactions which release energy from the chemicals into the surroundings. This energy is usually released as heat, so the surroundings get hotter. Handwarmers... WebIn a nutshell, exothermic reactions result in the release of energy because the reactants undergo a transformation that results in products that have a lower energy state. It is necessary for the reactants to be able to reach the transition state for the reaction to take place, and this state is almost always only attainable when the ...
