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

Answer»

VISIBLE REGION
infrared region
ultraviolet region
microwave region

SOLUTION :Energy E = hv
`therefore v=(E )/(h)=(11eV)/(6.62xx10^(-34)JS)`
`therefore v=(11xx1.6xx10^(-19)J)/(6.62xx10^(-34)Js)`
`therefore v=2.6586xx10^(15)Hz`
which is in ultraviolet region.
