    @TheForgottenArchitect they are all equilibrium expressions and they are temperature dependent; however, they are different in the sense for the quantities that they measure. for instance Ka is a measure of the relative tendency for a compound to give up it's proton, acidity. Keq/kc is the general equilibrium constants telling you which side of the reaction is favored. Keq >1 means products are favored at equilibrium and the reaction goes to the right. Keq < 1 means that the reactants are favored at equilibrium. while Keq = 1 means that they're equally favored both products/reactants.

    Am I correct in that Ka and Kc are calculated in basically the same manner?

    @TheForgottenArchitect so basically Kc is used for concentrations of a substance and Kp is used for pressures (c stands for concentration and p for pressure). Pure liquids and solids are pure and therefore do not have a concentration, so they cannot be used for Kc. do you know how you would get these values?

    It involves the moles of each product and reactant, correct? For example, [A]^2*[B]^2 / [AB]^2 And you would substitute the moles of each inside the brackets

    yes but remember the [ ] those brackets mean concentration so it would be mol/L

    Right, yes. Anyways, I think I have a good grasp now. Thank you!
