Answer:
The reaction is exothermic as the reactant have more energy than the product. Representing energy was released to the surrounding.
Step-by-step explanation:
In exothermic reaction energy is released to the surrounding when a product is formed. From the diagram we can see the energy revel decreased when the product was formed. Therefore, representing its exothermic.
So, your final answer should be
The reaction is exothermic as the reactant have more energy than the product. Representing energy was released to the surrounding.
