The diagram below shows the potential energy changes for a reaction pathway. Part 1: Does the diagram illustrate an enothermic or an exothermic reaction? Give reasons to support your answer.

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

Brainliest if you give the definition of endo and exothermic reactions, and how you know the change in enthalpy even if you put nothing else.​
