For the Arrhenius Equation, why is A approximately = 1 in most cases in this class?

Are you referring to the frequency factor? I think it is A=Zp but it is not usually calculated so it is just left as 1.

The "A" component is a probability out of a total 1.00, and represents the chance that the molecules are in the correct orientation when they collide.

I think we're making the experimental assumption that A doesn't adversely affect reactions modeled with the Arrhenius equation.
