Explanation:

When the energy of reactants is more than the products then the chemical reaction is known as exothermic reaction and the value of delta H is negative.

Whereas when energy of reactants is less than the energy of products then the chemical reaction is known as endothermic reaction and the value of delta H is positive.

Thus, we can conclude that when the products of a reaction have more energy than the reactants the reaction is endothermic and the δh is positive.
