The manganese(II)-catalyzed redox reaction between cerium(IV) and thallium(I) is thought to proceed by a three-step mechanism: Ce4+(aq) + Mn2+(aq) --> Ce3+(aq) + Mn3+(aq) (slow)Ce4+(aq) + Mn3+(aq) --> Ce3+(aq) + Mn4+(aq)Mn4+(aq) + Tl+(aq) --> Mn2+(aq) + Tl3+(aq) (a) If the first step of this mechanism is rate-determining (slow), choose the correct rate law for the overall process.

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. The chemical formula of methyl bromide is CH3Br. Why does methyl bromide per-form effectively as a fire extinguishing agent? d. A potential risk of inhalation toxicity may occur to individuals that…
