Consider this energy diagram:

d. Is the overall reaction endothermic or exothermic?

Video transcript

Welcome back everyone in this example, we need to determine whether our reaction is endo thermic or exo thermic based on our energy diagram. So looking at our energy diagram, we can see that energy which is recorded on our y. Axis of our products, is much lower compared to the energy of our reactant, which is at a much higher energy. So because we can say that the energy of our reactant is greater than the energy of our products, we can say that therefore there is less energy needed to break the bonds of our reactant then is released when the bonds of our products are formed. And so what we're saying is that more energy is actually being released in this reaction. And so we would say therefore we have an exo thermic reaction. And so our final answer is going to be that this reaction is X. A. Thermic based on the diagram. So this is our final answer. If you have any questions, please leave them down below. And I will see everyone in the next practice video.
