Skiing Hand Warmers. Once a year, Professor Dr. Sven Köttlov loves to go skiing with his students in the mountains of Jofostan. Before going, he retires to his basement in his small but adequate university housing to make hand warmers for everyone. B. Opegdra, A.M.R.P. Journal of Chemical Elevation on Time, D01:10.1021/acs.jchemed.8600012. J. Gordon and K. Chancy, J. Chem. Educ., 82(7), 1065 (July 2005). Here he mixes iron (steel wool), sodium chloride, and a few other proprietary ingredients, then seals them in an airtight Ziploc® compartment. When the warmers are needed, the bag is broken and the iron is exposed to air generating heat by the exothermic reaction

To determine the reaction kinetics, a steel wool sample was weighed, cleaned, and put in a sealed container where the percent of oxygen was measured as a function of time and the following data was recorded:

For a specified steel wool weight and surface area, the proposed relationship for the percent oxygen in the bag as a function of time is
[% O2]=3 exp(~kt)
a. Assuming the surface area of steel wool is approximately constant and the bag is sealed, use the CRE algorithm to derive Equation.
b. Compare the rate law and data. By inspection, without carrying out any data analysis, can you determine immediately that the rate law is correct or not? Explain.
c. Use the data to determine the rate law and rate-law parameters.
d. The data shows the reaction is virtually complete after 25 minutes, while the students will be skiing for 5–7 hours. Professor Köttlov had finger nail polish removed from his nails with acetic acid immediately before performing the experiment. It is known that acid accelerates the reaction. Can you take this information into account? If so, how would you do it?
