A in the Arrhenius Equation

[Jacob Bershatski 4C]

In the Arrhenius Equation, I'm kinda confused what A means and when to apply it. Can someone help me out plz?

[Dhwani Krishnan 1G]

it is the frequency factor, and basically gives the frequency with which reactants will collide in the correct orientation in order to form product.

[Rhea Churi 4K]

It gives the frequency at which the reactants collide correctly to form products.
I'm pretty sure for this class A will either be given or just equal to 1.

[Rachana Jayaraman 1H]

A is the frequency factor and represents the number of collisions with correct orientation over time. It has to be given to you since it depends on the reaction and is used mainly for the Arrhenius equation: K = Ae^(-Ea/RT) or lnK = -(Ea)/(RT) + lnA.

A is just the frequency factor. Basically, if A increases the rate will increase. If you're looking at a plot, lnA is the b in y=mx+b, or the y-intercept.
