Calculate the wavelength of light required to break the bond between two chlorine atoms in a chlorine molecule. The Cl- Cl bond energy is 243 kJ `mol^(-1) (h=6.6 xx10^(-34)Js,c=3xx10^8m//s, ` Avogadro's number `=6.02xx10^(23)mol^(-1)` )

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`
