Given that [Ni(NH₃)₆]²⁺ has an absorption at 926 nm and [Cr(NH₃)₆]³⁺ has an absorption at 463 nm, what is the ratio of D_o in the nickel compound compared to the chromium compound

Question

Quizplus · Accepted Answer

The energy of absorption is inversely proportional to the wavelength. Since the nickel compound absorbs at a longer wavelength (926 nm) compared to the chromium compound (463 nm), the energy (D_o) for the nickel compound is lower. Specifically, the ratio of wavelengths (926/463) is 2, so the energy (D_o) for the nickel compound is 0.5 times that of the chromium compound.
