The crystal field splitting energy of [ Co ( oxalate )₃ ]³⁻ complex is ' n ^ times that of the [ Cr ( oxalate )₃ ]³⁻ complex. Here ' n ^ is _ _ _ _ . (Assume ₀ P )

Step-by-step solution

The Crystal Field Stabilization Energy (CFSE) is calculated based on the electronic configuration of the central metal ion in the octahedral field. For [Co(ox)₃]³⁻ : Cobalt is in +3 oxidation state. Co³⁺ has a d^6 configuration. Given ₀ P , it is a low spin complex. The electrons fill the t_ 2g level first. Configuration: t_ 2g ^6 e_g^0 . CFSE for Co³⁺ = 6 (-0.4 ₀) + 0 (0.6 ₀) = -2.4 ₀ . For [Cr(ox)₃]³⁻ : Chromium is in +3 oxidation state. Cr³⁺ has a d^3 configuration. Configuration: t_ 2g ^3 e_g^0 . CFSE for Cr³⁺
