Please Help! I will mark brainliest! The diagram shows the potential energy changes for a reaction pathway.

Part 1: Does the diagram illustrate an endothermic or an exothermic reaction? Give reasons in support of your answer.

Part 2: Describe how you can determine the total change in enthalpy and activation energy from the diagram and if each is positive or negative.

When the energy of the products is higher than the energy of the reactants then it means the reaction is endothermic. In the graph it can be seen as having a higher energy at the end than the initial energy. If the opposite is observed then the reaction is exothermic.

Explanation:

hope this helps im trying to virtuoso so i need brainliest
