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
