The process that is an example of an exothermic reaction is burning sugar.
Further Explanation;
Energy changes in chemical reactions
- Chemical reactions are accompanied by energy changes, as energy is either absorbed to break chemical bonds or released when bonds are formed.
- Chemical reactions are therefore classified as endothermic reactions or exothermic reactions.
Exothermic reactions
- Exothermic reactions are types of reaction that release energy to the surrounding.
- In these reactions energy is released when new bonds are formed during the reactions. More energy is released when bonds are formed in the products than is used to break bonds in the reactants.
- Therefore exothermic reactions have a negative (-) enthalpy change (ΔH).
Endothermic reactions
- Endothermic reactions are type of reactions that absorb energy from the surroundings.
- In these type of reactions more energy is absorbed when bonds of the reactants are broken than the energy released when bonds of the products are formed.
- Endothermic reactions have a positive (+) enthalpy change (ΔH).
