Total: 50

The diagram represents

Solution:

Concept:

An energy-profile diagram indicates whether heat is absorbed or released during a reaction.

Explanation:

In the diagram, the products are at a higher energy level than the reactants, so

E_{\text{products}} > E_{\text{reactants}}

This shows that energy is absorbed during the reaction.

Therefore, the reaction is endothermic.
