Answer:
[tex]4.0932672025\times 10^{-17}[/tex]
Explanation:
[tex]E_a[/tex] = Activation energy = 160 kJ
T = Temperature = 510 K
R = Universal gas constant = 8.314 J/mol K
The fraction of energy is given by
[tex]f=e^{-\dfrac{E_a}{RT}}\\\Rightarrow f=e^{-\dfrac{160000}{8.314\times 510}}\\\Rightarrow f=4.0932672025\times 10^{-17}[/tex]
The fraction of energy is [tex]4.0932672025\times 10^{-17}[/tex]
