# Will This Be on the Chem SAT II?

Will questions about Ksp or Ka require you to use variables to solve for something?

For example, one Barrons problem required you to set up this equation:
Keq = ((2x)^2)/((3 -x)(3 - x)) = 45.9

This equation was made based on the information from the problem. But aren't these more AP level? It's not the math I'm worried about. I just haven't taken AP Chem yet, and I'm hoping equilibrium constant problems aren't too tough

Yamster, I'm taking chem in october too and I saw a problem like that. I hope its not on there as well.. The concept confuses me.

@ansrox: Hope you're right
@Model T: Yeah, I don't think it is. Hopefully more people answer. Then I'll be more reassured.

What about questions where about equilibrium where you have to set up ICE charts?

I saw that in AP Chem videos (from the AP Chem CTY course I'm enrolled in), and "ICE" wasn't in the Barrons SAT II book, so I'm pretty sure it's not on the SAT II.

I highly doubt that such a problem would show up on the chem sat subject test, mainly because no calculators are allowed.
