Webexothermic. A reaction that converts chemical energy to thermal energy (heat is given out) Exothermic reaction. A reaction that converts thermal energy to chemical energy (heat is taken in) Endothermic reaction. Examples of exothermic changes. Combustion, neutralisation, displacement, condensation. Examples of endothermic changes. WebSo it must be an exothermic reaction then. For a simple answer, an acid, likes do donate its H X + ions, and a base likes to give off its O H X − ions. The bond enthalpy of the A-H and B-OH bonds are low. Now the H X + a n d O H X − fuse to form a water molecule, giving rise to new bonds, hence is an exothermic process.
