Part 1: Looking at the diagram above, what can you tell me about the type of reaction it is? Is this exothermic or endothermic? How do you know? Make sure you support your answer by using the diagram. Part 2: Thinking about enthalpy and a change in enthalpy, explain how you could find the total change of enthalpy based on this diagram. Is the enthalpy positive or negative?

Part 3: How could you find the activation energy? Is the activation energy positive or negative?
