(a). Derive the overall kinetic expressions for the four combinations of the two possible initiation steps (1 or 1a) and the termination steps (5 or 6).
(b) Compare the overall rate constants at T = 873 K with the experimental value of 8.4 × 10-4 s-1.
(c) Show that the ratio of the rates of reaction 5 and 6 is given by
After the addition of a large excess of the acid solution (in comparision with the acid volume needed to reach the equivalence point). Tell how many milliliters of acid are required to reach the equivalence point.
In an oversight in the experiment Jamie did not add the 4-5 additional drops of 6M HNO3. As a result, will the reported number of moles of oxygen be too high or too low in the final product. Explain.
A reference book gives the normal freezing point of naphthalene as 80.2 ?C. Your sample of naphthalene began to form crystals at 79.1 ?C on your thermometer. Give two reasonable explanations for this observation.
