Δo RhCl-36 is 243 kJ/mol λ=(6.626 ×10-34×3×108/234×103) = 511 nm. Nearest color is orange.

Q. The value of $Δ_{o}$ for $R h C l_{6}^{3 -}$ is $234$ kJ/mol. What wavelength of light will promote an electron and the colour of the complex respectively are

$511$ nm, Blue

$525$ nm, Green

$645$ nm, Yellow

$511$ nm, Orange

$Δ_{o} R h C l_{6}^{- 3}$ is 243 kJ/mol
$λ = \frac{6.626 \times 1 0 ^{- 34} \times 3 \times 1 0 ^{8}}{234 \times 1 0 ^{3}}$
$= 511$ nm. Nearest color is orange.
