In a dissociation reaction, exothermic reaction give off heat while an endothermic reaction absorbs heat from the surroundings.
An exothermic reaction is a reaction in which heat is given as the react ion proceeds towards formation of products.
An endothermic reaction in which heat is absorbed when reactants form products.
In a dissociation reaction, ionic compounds dissociate into the component ions when dissolved in water.
An exothermic dissociation reaction will produce heat since the crystal lattice energy is large.
An endothermic dissociation reaction will absibe heat since the lattice energy is small.
Therefore, an exothermic reaction give off heat while an endothermic reaction absorbs heat from the surroundings.
