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
`E=11eV=11xx1.6xx10^(-19)J=hv or v=(11xx1.6xx10^(-19))/h=(11xx1.6xx10^(-19))/(6.62xx10^(-34))=2.65xx10^(15)Hz`
This frequency radiation belongs to ultraviolet region.

When an electric discharge is passed through hydrogen gas, the hydrogen molecules dissociate to produce excited to produce excited hydrogen atoms. These excited atoms emit electromagnetic radiation of discrete frequencies which can be given by the general formula vecv=109677[(1)/(n_(i)^(2))-(1)/(n_(f)^(2))] What points of Bohr's model of an atom can be used to arrive at this formula? Based on these points derive the above formula giving description of each step and each term.
