Crystal field theory explains that the colour of coordination compounds is due to d-d transition of electrons. 1. The crystal field stabilization energy (CFSE) is the stability that results from placing a transition metal ion in the crystal field generated by a set of ligands. It arises due to the fact that when the d-orbitals are split in a ligand field (as described above), some of them become lower in energy than before with respect to a spherical field known as the barycenter in which all five d-orbitals … involved lobe failure

"WebMar 17, 2024 · Re: What are the units of activation energy? Look at the Arrhenius equation, k = A*e^ (-Ea/RT). R has units of J*K-1*mol-1 while T has units of K. The K will cancel out so what you have left is J*mol-1. You want to cancel both of these out which can be done with Ea with units of J*mol-1. " - Crystal field activation energy
