7D.2 collision theory equation?

[Sue Bin Park 2I]

will we have to work with the big equation for rate constant given in this section? from my understanding, we just need to be familiar with qualitative concepts of the collision theory (and activated complex model), right?

None of the homework questions in this section required you to use the collision frequency equation so I am assuming that being familiar with the concepts is more important.
