Frequency factor A

[Ashley McClearnen 1B]

Can someone please explain what the frequency factor, A, is and what it tells us.

[Katelyn Pham 4E]

In the book it says "A is a measure of the rate at which molecules collide" and this rate refers to the frequency of molecules colliding.

[Rogelio Bazan 1D]

Since Dr. Llavelle went over this at the end of the lecture I did not get great notes on it, but what I did get was that 'When they collide, it is Frequency Factor A'. So I assume that Frequency A is in reference to the rate at which the molecules collide. Hope this helps.

in lecture today it was explained that frequency factor, A, has to do with reactants must have correct orientation when they collide. Dr. Lavelle also mentioned when A increases k decreases

[Max Hayama 4K]

I believe Professor Lavelle mentioned that the frequency factor is the percent of successful collisions. So if 10% of collisions are successful based off orientation, the frequency factor, A, will be .10.

In the book, A is just called the pre-exponential factor. I think it will become clearer in the next lecture as we get into collision theory. Then you see what constants are included in A.

[LorenzoDuvergne3I]

Were any of the other terms mentioned in lecture today?

[sophiebillings1E]

I'm pretty sure its the percent of successful collisions.
