Potential Energy Diagram Practice Endothermic and Exothermic Reactions

Students will be given two Potential Energy Diagrams -- one Endothermic, one Exothermic. They will have to read the graph and determine if the graph is showing an endothermic or exothermic reaction, justify why it is so, then calculate the heat of reaction (delta H), activation energy (Ea), reverse activation energy, answer four conceptual multiple choice questions, and then determine if 9 real-life scenarios demonstrate exothermic or endothermic reactions.

This worksheet is suitable for the conclusion of the introductory lesson to be worked on in class, or as a reinforcing homework assignment. This would be ideally appropriate for a High School Chemistry or Physics class.

I have included the Answer Key for this document.
