To determine the maximum wavelength of electromagnetic radiation that can break the weakest bond in the compound ICl2F+2, we need to find the bond with the lowest bond energy.
From the given bond energies, we can see that the weakest bond is the F-F bond with an energy of 160 kJ/mol.
To convert the bond energy into joules per bond, we divide the bond energy by Avogadro's number (6.022 × 10^23 mol^-1). Therefore, the energy per bond is:
E_per_bond = 160 kJ/mol / (6.022 × 10^23 mol^-1) = 2.656 × 10^-19 J
To calculate the maximum wavelength of electromagnetic radiation required to break this bond, we can use the equation:
λ_max = hc / E_per_bond
Where:
λ_max: maximum wavelength of radiation (in meters)
h: Planck's constant (6.626 × 10^-34 J·s)
c: speed of light (3.00 × 10^8 m/s)
Plugging in the values:
λ_max = (6.626 × 10^-34 J·s * 3.00 × 10^8 m/s) / (2.656 × 10^-19 J)
Calculating this expression will give you the maximum wavelength in meters.
