Question

It takes to break a carbon-iodine single bond. Calculate the maximum wavelength of light for which a carbon-iodine single bond could be broken by absorbing a single photon.

Answer 1

502.9 nm

Step-by-step explanation:

Energy to break to the bond of carbon-iodine is not given assuming it to be 238KJ/mol

we know that

ΔE= hυ

also, υ= c/λ

therefore λ = hc/ΔE

`= (6.626*10^(-34)*3*10^8)/(238*10^3)\\=0.08352*10^(-29) m mol`

also, 1 mol = 6.022×10^23 atoms or molecules

`\lambda= 0..08352*10^(-29)*6.022*10^(23)\\=502.9 *10^(-9)m\\=502.9 nm`
