1. CHEM 433 – 12/1/10 IX. Chemical Kinetics (Ch. 22 & Handout)
• Determining Rate Laws (22.1, 22.3)
- Integrated Rate Laws
- graphical methods
• Elementary Reactions:
- “order” vs. “molecularity”
• Connection between EQ and kientics
(pre-temp dependence version…)
EXAM #5 is ….?
HW #11 is out – review sheet/web update ASAP.

2. Consider the following reaction, and the table of (initial) rate data:
H2O (g) SO3 (g)  H2SO4 (g).
a) Write rate law in the blank below.
RATE = __________________________
b) Calculate the value of the rate constant, w/ the proper units.
c) Does the reaction occur as written, in a single elementary step? Explain.
[H2O]
[SO3]
Rate
0.01 M
1.0 x 104 M/sec
0.02 M
4.0 x 104 M/sec
2.0 x 104 M/sec

3. Show that for: RATE = k [A]2
A plot of 1/[A] vs. t will be linear, w/ a slope = k.
Also show that the half-life is given by:
t1/2 = 1 / k[A0]
