One requires $11eV$ of energy to dissociate a carbon monoxide molecules into carbon and oxygen atoms. The minimum frequency of the appropriate electromagnetic radiation to achieve the dissociation lies in

detailed solution

Correct option is C

Here it is given, the energy required to dissociate a carbon monoxide molecule into carbon and oxygen atoms is  E=11eV. We know that E=hϑ where h=6.62×10−34Js  and ϑis frequency  ⇒11eV=hϑ ⇒ϑ=11×1.6×10−196.62×10−34=2.65×1015HzThis frequency radiation belongs to ultra violet region *** when energy of the given photon is in electron volt  then   wave length will  be given by λ=1243211=1130.18×10-10 m    this wavelength of the photon is in ultra violet region  because  E=hcλ   so λ=hcE =12432E   in  A0 .
