One requires 11eV of energy to dissociate a carbon monoxide molecule into carbon and oxygen atoms. The minimum frequency of the appropriate electromagnetic radiation to achieve the dissociation lies in ultraviolet region. Explanation: Given energy required to dissociate a carbon monoxide moleule into carbon and oxygen atoms E = 11eV We know that E = hv, where h = 6.62 $\times$ 10–34 J – s v = frequency $\Rightarrow$ 11 eV = hv $\Rightarrow$ ` v = (11 xx 1.6 xx 10^-19)/(6.62 xx 10^-34) J = 2.65 xx 10^15` Hz This frequency radiation belongs to ultraviolet region.
