### Calculation for pre-exponential factor A

Are we responsible for knowing how to calculate A, or will the value be given to us?

I think it would be given because he didn't really say we really needed to know it?

It would not be possible for us to calculate A, however we could compare A for different collisions. For example, the collision of two H atoms would have a higher A than a more complex collision.

Even though the assigned reading goes into this calculation in-depth, I doubt that we will have to know how to calculate it as he hasn't gone over it in lecture and there have been no homework problems that deal with the topic.
