What is the longest wavelength of radiation that possesses the necessary energy to break the o-o bond?
1 answer:
Answer:
The longest wavelength of radiation is 241nm and it lies in ultraviolet region.
Explanation:
The minimum energy required to break o-o bond is 495kJ/mole.
The photon does not have mass and the energy of the single photon depends entirely on the wavelength and is given by
e =hc/λ
where, h is the Planck constant,
c is the speed of light
e is the energy of photon
λ is the wavelength
From the Planck formula we can understand that energy of the photon is quantized.
E = e.Nₐ
e = E/Nₐ = = 8.22*10⁻¹⁹ J/photon
λ = hc/E=
λ = 2.41*10⁻⁷ m = 241 nm
The longest wavelength of radiation is 241nm and it lies in ultraviolet region.

Hi there! :)
In the solar system, we can categorize the planets as such:
Inner planets: Mercury, Venus, Earth, Mars
Outer planets: Jupiter, Saturn, Uranus, Neptune
The Inner planets are the only planets that consist of solid rock. They also do not have rings and have impact craters due to their early formation.
In comparison, all of the outer planets are primarily made up of gaseous material and contain rings.
Therefore, the correct choice is B.
