N-N 160
C-C 350
Express your answer in meters.
Still having problems with this one! Any thoughts!
4.6*10^-7
thats not it for me :(
To calculate the maximum wavelength of electromagnetic radiation capable of breaking the C-N bond in lysine, we need to determine the bond energy of the C-N bond. Given the average bond energies, we can subtract the bond energy of the C-C bond from the bond energy of the N-N bond to find the bond energy of the C-N bond.
C-N bond energy = N-N bond energy - C-C bond energy
C-N bond energy = 160 kJ/mol - 350 kJ/mol
C-N bond energy = -190 kJ/mol
Now, we can use the equation E = hc/λ to find the maximum wavelength (λ) that corresponds to the bond energy (E). Here, h represents Planck's constant (6.62607015 × 10^-34 J·s) and c represents the speed of light (2.99792458 × 10^8 m/s).
Rearranging the equation, we get λ = hc/E.
Substituting the values, we have:
λ = (6.62607015 × 10^-34 J·s * 2.99792458 × 10^8 m/s) / (-190 kJ/mol * 1000 J/kJ)
λ ≈ 3.13017632 × 10^-11 m
Therefore, the maximum wavelength of electromagnetic radiation capable of breaking the C-N bond in lysine is approximately 3.13017632 × 10^-11 meters.
