Answer:

Endothermic reaction

Explanation:

(a) Endothermic reaction: These are reactions that absorb heat from the surrounding during a chemical reaction. The enthalpy change for endothermic reaction is always positive,  and the energy level of the product is higher than that of the reactant

(b) Exothermic reaction: These are reactions that release heat to the surrounding during chemical reaction. The enthalpy change for exothermic reaction is always positive, and the energy level of the product is lower than that of the reactant.

From the diagram in the question,

Since the energy level of the product is higher than that of the reactant then the reaction is an endothermic reaction and as such, ΔH is positive
