Ethylene oxide is a reagent important in many chemical processes and also a major component in explosives. It is formed through the partial oxidation of ethylene: C2H4 + 1/2 O2 → C2H4O k1= 5665 s-1 However, ethylene can also undergo a combustion reaction: C2H4 + 3/2 O2 → CO2 + H₂O k2 = ? s] = ? 5-1 Assuming both reactions obey first order kinetics with excess oxygen and that after 9.6 minutes [C2H4O]/[CO2] = 7.9, what is the rate constant k2? In water, the fluorescence quantum yield and observed excited-state lifetime of tryptophan are Of = 0.19 and to = 2.6 ns, respectively. What is the fluorescence rate constant (in s-1) of tryptophan?
