Reaction Energy Diagrams (17 min)

This tutorial introduces the concept of Reaction Energy Diagrams and the wealth of information that they provide. (Runtime = 16:47)

Student Learning Outcomes
After viewing this tutorial and practicing problems from this website and your textbook, you should be able to:
• Identify the various parts of a reaction energy diagram and determine whether the reaction, as well as each steps of the reaction, is endothermic or exothermic.
• Draw approximately correct reaction energy diagrams when provided with the mechanism of a reaction.
• Compare reaction energy diagrams of two or more reactions and infer various relative features of the reactions (e.g., which reaction is more selective?) from your comparison.

Practice Problems
Here are some problems to get you started. You should first try each on a piece of paper. Then, place your cursor over the graphic and click on right arrow that appears to see the answer. The right and left arrows allow you to move back and forth between problems. Please note that these are not the only types of problems/questions that exist on this topic. Refer to your textbook and any problems your instructor provides you for more practice with this subject.
