Use the References to access important values if needed for this question. Estimate the wavelength of maximum absorption for the octahedral ion hexacyanochromium(III) from the fact that light transmitted by a solution of it is yellow. Use the color wheel to the right to estimate the wavelength. nm From this, estimate the energy difference between the t_2g and e_g orbitals, Delta_o (in kJ mol^-1). KJ mol^-1
