From the graph, we see that the final position of the curve is higher than the original height of the curve, meaning the products have more energy than the reactants.
Hence <em>energy was added for the reactants to become the products</em>. This is why the reaction is endothermic, because the products retained some of the supplied energy.
Part of the energy supplied was used to overcome the activation energy (the peak of the curve). However, this extra energy is recuperated as heat once the product is formed.
Answer:
you have to show the prism
