endothermic reaction
exothermic reaction

Explanation:

In an endothermic reaction, the products have higher potential - energy than the reactants, and $\Delta H>0$. In an exothermic reaction, the products have lower potential - energy than the reactants, and $\Delta H < 0$. Looking at the left - hand diagram, the potential energy of the products is higher than that of the reactants.

Answer:

Endothermic Reaction
