The value of Δ for [ Rh ( Cl )6]3- is 243 kJ mol -1. What wavelength of light will promote an electron from the t2 g set to e g set? (A) 483 nm (B) 492 nm (C) 122 nm (D) 729 nm

Tardigrade Admin · Accepted Answer

Δ=(h c/λ), for per mole (λ)=(h c × NA/Δ) .

Q. The value of $Δ$ for $[R h (Cl)_{6}]^{3 -}$ is $243 k J m o l^{- 1}$ . What wavelength of light will promote an electron from the $t_{2 g}$ set to $e_{g}$ set?

483 nm

492 nm

122 nm

729 nm

$Δ = \frac{h c}{λ}$ , for per mole $(λ) = \frac{h c \times N _{A}}{Δ} .$
