A chemical reaction is said to be exothermic when it releases energy in the form of heat The system reaction releases heat to the surroundings as the reactants transform into products In thermochemistry an exothermic reaction is a quot reaction for which the overall standard enthalpy change H is negative quot 1 2 Exothermic reactions usually release stored energy as heat
When a chemical reaction happens energy is transferred to or from the surroundings When energy is transferred to the surroundings this is called an exothermic reaction and usually feels hot If energy is released by a reaction the reaction is exothermic If energy is absorbed by a reaction the reaction is endothermic When petrol burns via a combustion reaction the energy released can be
