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


Given:


Energy required to dissociate a carbon monoxide molecule E=11eV


Explanation


Each quantum of energy provided by electromagnetic radiation is given by the equation:



Where h is the plank’s constant and ν is the frequency of incident radiation. To dissociate a carbon monoxide molecule, 11 eV of energy is required, therefore the frequency of radiation associated with that energy is





The ultraviolet region has the frequency range to , and the frequency for 11 eV is . Thus, the minimum frequency of the appropriate radiation lies in the ultraviolet region.
