Expert Answer
We know that,
K=Ko e-(Ea/RT)
Hence, We can write the equation according to the question as:
Make a ratio of the corresponding Arrhenius equations, canceling the Ko as instructed:
k(cat) / k(uncat) = e-(Ea/RT)cat / e-(Ea/RT)uncat
Just substitute:
R=8.314472 J/K-mol
T=293.15 K for T
Ea=20000 J/mol for E(cat)
Ea=75000 J/mol for E(uncat)
We can obtain:
k(cat) / k(uncat) = e-(20000/8.314*293)cat/e-(75000/8.314*293)uncat=6339083268.076277
Just substitute:
R=8.314472 J/K-mol
T=293.15 K for T
Ea=20000 J/mol for E(cat)
Ea=75000 J/mol for E(uncat)
We can obtain:
k(cat) / k(uncat) = e-(20000/8.314*293)cat/e-(75000/8.314*293)uncat=6339083268.076277
