2. What do these graphs represent?
Questions:
What do these graphs represent?
Where is DH?
What is the difference between these graphs?
What is present at the peak of each graph? What does this represent?
What energy is needed to reach this point?
How does that energy change the rate of reaction?
How?
Transition State
Aka activated complex DH

3. Temperature’s effect on reaction speed
Questions: What does this graph show? What is the difference in the two lines? How is kinetic energy related to speed? What does that mean about the difference between speeds of the molecules the two lines represent? What must be true to allow a reaction to occur? How is this represented on the graph? Which line has more molecules past the activation energy? What does that mean about the speed of the reaction? Why?
Atkins

4. Arrhenius Equation y= m x + b Slope is Questions:
What is this equation saying?
How can we make this linear?
What would this graph look like?
What would the slope and y intercept be?
What would the graph look like if you had an activation energy that was higher? Lower?
If you know K at one temperature how do you find it at another?
y= m x b
y=mx+b
Ln(k)
Slope is
1/T

5. Concentration Catalysts
At constant temperature what can we do to change the rate of reactions?
Concentration
Catalysts

6. Catalysts
Questions: How do these graphs differ if we catalyze the reaction? What does that mean in words? How do catalysts do this? What are two of the major types of catalysts? DH
