PLEASE HELP QUICKLY The diagram shows the potential energy changes for a reaction pathway. (10 points)

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.

1. The reaction is an endothermic one because you can see that after the reaction occurs, the enthalpy is greater.

2. The total change in enthalpy is positive since it's endothermic, and you can calculate it by seeing the difference between A and C (C-A)

The activation energy can be found by subtracting the point of activation (the higher line) by the initial enthalpy. In this case it would look like B-A
