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?

![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-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

tryptophan?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F157da969-9426-4164-bca8-75691181cb50%2F740bafb8-a6ba-4d93-8453-e62e28cb99b7%2Fc8l54x_processed.jpeg&w=3840&q=75)
