The questions below refer to the following diagram: 
-Why is this reaction considered to be exothermic?

Quizplus · Accepted Answer

An exothermic reaction releases energy, meaning that the products have a lower energy than the reactants. In the diagram, energy difference B (the difference in energy between the reactants and the products) is greater than energy difference A, which means that the products have less energy than the reactants. Energy difference C is irrelevant to determining whether the reaction is exothermic or endothermic.
