Answer:
The wavelength of sunlight is required to break the bond in one oxygen molecule is 242 nm.
Explanation:
Energy required to break the 1 mol oxygen-oxygen bond:
=495 kJ=495000J
1 mol = molecules
Energy required to break 1 molecule of oxygen molecule= E
=
The energy required to break the 1 molecule of oxygen is equal to enrgy of one photon of a sunlight.
where,
= wavelength of the light
E = energy of the photon
h = Planck's constant =
c = speed of light =
The wavelength of sunlight is required to break the bond in one oxygen molecule is 242 nm.
