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

A

visible region

B

infrared region

C

ultraviolet region

D

microwave region

Text Solution

Verified by Experts

The correct Answer is:
C
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.
