CFT: Crystal Field Activation Energy Explained

[Bladibla]

Is the Crystal field activation energy and Crystal Field stabilisation energy the same thing? I've been looking all over the textbooks but I can't a good explanation for the former.

Where have you seen the term "crystal field activation energy"?

 

[Bladibla]

In a past exam paper.

The exact question was:

''Explain what is meant by 'crystal field activation energy' and how it affects the stability of complexes.''

 

[chemisttree]

That is the first time that I have seen it called by that term. I have always seen it as simply "activation energy" for species "X". Try googling "ligand field activation energy".
