Calculate the wavelength of the radiation that would cause photo dissociation of chlorine molecule if the `Cl-Cl` bond energy is `243kJ//mol`.

Text Solution

Verified by Experts

The correct Answer is:
`4.9xx10^(-7)m`
`(243)/(96.368)=(1240)/(lambda(nm))`
`lambda=(1240xx96.368)/(243)=491.75xx10^(-9)m~~4.9xx10^(-7)m`
