- Chemistry of Fire Extinguishing Agents: Review and answer the below scenerios. a. The OSHA regulation at 29 C.F.R. §1910.162(b)(5) requires employers to provide a predischarge-employee alarm system to alert employees if a carbon dioxide concen-tration of 4% or greater is released from a fixed extinguishing system in a workplace. What is the most likely reason OSHA enacted this regulation? b. At 14 C.F.R. §121.265, FAA allows carbon dioxide to be used as a fire extinguish-ing agent onboard aircraft, provided that provisions are made to prevent harmful concentrations from entering any personnel compartment. Use Table 5.6 to deter-mine whether adverse health effects are likely to be experienced by a crew member who is confined to a compartment in which the air contains 8, carbon dioxide. c.

- (g) How does simple collision theory (SCT) for reaction kinetics qualitatively predict the Arrhenius temperature dependence of the rate coefficient? Explain BRIEFLY the principal deficiencies of SCT. A derivation of more complex theories is not needed.UCI Chemistry researchers, Prof. F. Sherwood Rowland and Dr. Mario Molina werefirst to discovered in 1973 that chlorofluorocarbons (CFCs) were depleting the Earth’sozone layer when released into the atmosphere. Once they reach the stratosphere, Clis released from the CFCs molecules by interaction with UV light. Free Cl atoms areable to react with ozone in a catalytic cycle that converts O3into the more stable O2.It is estimated that a single Cl atom is able to react with∼100000 O3molecules.Although CFCs production was banned in 1996, there are still a substantial numberof motor vehicle air conditioners (MVACs) that use CFC-12 (CF2Cl2) as refrigerant.The average CFC-12 emission rate from operating MVACs has been estimated tobe 59.5 mg per hour per vehicle (Zhang et al.Environ. Sci. Technol. Lett.2017).How much chlorine, in kg, is added to the atmosphere in a year due to 100 millionMVACs using CFC-12 as refrigerant?What does "shape-selective catalysis" mean to you? Zeolites make effective shape-selective catalysts; why?
