Keq = kf1*kf2*kf3 / Kr1*kr2*kr3 = [overall products]^coefficient / [overall reactants]^coefficient

= law of mass action

At constant temp., a change in pressure causes a change in volume and vice versa.
Has the most effect on gases as most compressible

↑  Pressure, ↓ moles of gas, ↓ volume - reaction favors side where fewer moles of gas are present

↑  Volume, ↓ Pressure, ↑ moles of gas - reaction favors side where more moles of gas are present

Each salt has its own disinct Ksp, which shows its solubility in aqueous solution

Ksp = [A]^m[B]^n
where A and B = ions in solution
m and n represent there stoichiometric coeffectients in solution

Given the solubility of a salt, we see that Xmoles of salt/liter of solution can dissociate.

Using that information we can determine how many moles of each ion will form based on the dissociation reaction

Using those values we write the Ksp equation and fill in the blanks
