b) Problems 6.3, 6.10, 6.16, and 6.21
2) Calculate the integrated rate law for the product concentration in the unimolecular reaction A → P. Start
from the rate law to do so, and assume that there is no product present at time zero.
3) N20 decomposes according to the following equation:
2 N20(g) → 2 N2(g) + O2(g).
Under certain conditions, the rate of the reaction is 6.16-106 mol·L-'-s'. Calculate the values of
d[N2O]/dt, d[Nz]/dt and d[O2]/dt.
4) The reaction
SO,Cl2(g) → SO2(g) + Cl2(g) is first order and has a rate constant of k, = 2.24-10S s' at
320°C. Calculate the half-life of the reaction. What fraction of the reactant remains after being heated for
5.00 hours at 320°C? How long will a sample of SO;Cl2 need to be maintained at 320°C for
decomposition of 92% of the initial amount present?
5) In biochemistry, radioactive labeling is often used in kinetics experiments and as markers in gel
electrophoresis. You order a sample of Na;PO4 containing the radioisotope 3²P (tv/2 = 14.3 days). If the
shipment in transit is delayed for two weeks, how much of the initial activity will remain when you
finally receive the sample?
6) In geology and archaeology, potassium-argon dating is used to date sedimentary rocks. 4°K decays by two
pathways:
40K → 40CA+ electron
(89.3%)
40K → 40Ar+ positron
(10.7%)
The overall half-life of "K is 1.3-10° years. Estimate the age of sedimentary rocks with a 4°Ar:4°K ratio of
0.0102.
7) Application of Chemical Kinetics and Dynamics to Atmospheric Chemistry
Read the two attached Roaming papers ;
(No Straight Path: Roaming in Both Ground- and Excited-State Photolytic Channels of NO3→ NO + O2
