Question

The value of Δ₀ for \[\ce{RhCl^{3-}6}\] is 243 KJ/mol which wavelength of light will promote an electron from. The colour of the complex is ______.

Options

• Blue

• Green

• Yellow

• Orange

Answer 1

The value of Δ₀ for \[\ce{RhCl^{3-}6}\] is 243 KJ/mol which wavelength of light will promote an electron from. The colour of the complex is Orange.

Explanation:

Δ₀ \[\ce{RhCl^{3-}6}\] is 243 KJ/mol

E = `"hc"/λ`

λ = `(6.626 xx 10^-34 xx 3 xx 10^8)/(234 xx 10^3)`

= 511 nm

Nearest color is orange.
