Potential Energy Diagrams
1. What is the only component of a Potential Energy (PE) diagram that deals with kinetics (the speed of the reaction)? ____________________
2. If you add in a(n) _____________________ to the reaction, it will change the answer to Question 1 thereby increasing or decreasing the rate of reaction.
3. The answer to Question 2 has another important aspect/characteristic, what is it? __________________________
4. On the back of this paper, please show/draw the PE diagram for an endothermic reaction and label all appropriate components and then define them (make a list of word with definitions).
Reaction Mechanism
5. Def intermediate: ____________________________________________
6. If you are looking at the steps of an overall chemical reactions, explain how you can tell if you have an intermediate and/or a catalyst.
7. Most overall chemical reactions are multi-step (ie all the reactants do not react all at once). What is the reason why this is so? ________________________
8. If you want to increase the rate of the overall reaction, what step do you need to increase? __________________________ What do we call this step? ________________________
