The value of `Delta_0` for `RhCl_6^(3-)` is `243 kJ//mol` what wavelength of light will promote an electron from. The colour of the complex isA. (a) BlueB. (b) GreenC. (c) YellowD. (d) Orange

Answer» Correct Answer - D
`Delta_0RhCl_6^(-3)` is `243 kJ//mol`
`E=(hc)/(lambda)`
`lambda=(6.626xx10^(-34)xx3xx10^8)/(234xx10^3)`
`=511nm`. Nearest color is orange.
