That quantity frequency factor is going to be

dependent on a couple of things.

Number one it takes into account

the collision frequency.

Therefore it is called the frequency factor.

With that, you take into account the state of matter, for example.

Something that is in a gas state With that, you take into account the state of matter, for example.

Something that is in a gas state

free to move and they move very very rapidly

so they can collide with each other

but there is great distances between them.

But if they are in a liquid state

they still can move pretty quickly but they

much much closer together.

They will collide more frequently

so that takes into account the state.

If it is a solid, they do not move very freely

and that cannot collide very frequently. So that would

have a different frequency factor.

It also takes into account.

orientation of the molecules

because sometimes one collision even

if it has a lot of energy won't result in a reaction

and we see that here in the top

image. In the top image if they were to collide

no reaction would occur.

But if they collided and the green ran into the green

then there could be a reaction.

If there is an orientation necessary

to have a collision

that will come out in that Arrhenius equation.

In conclusion with lesson and out learning objective here

we see that there is mathematical relationship between temperature

activation energy and the rate constant k.

We saw how to graph it out

in order to obtain a linear relationship.

How to plug into a two point value equation

with a K1, T1

K2, T2

how to be able to obtain an unknown out of that equation.

Lastly we see how the frequency

factor A plays a role in rates of reactions. Lastly we see how the frequency
