Converting Kc between Chemical Reactions

[Adelyne_Tran_1J]

How do we convert Kc values(equilibrium constant) between different chemical equations with differing stoichiometric coefficients?

I'm not sure if this is what you're asking about, but when determining Kc by adding or subtracting reactions and then multiplying each reaction's Kc, you would raise Kc of whatever reaction is being added or subtracted to the power of the coefficient you multiply the whole reaction by. For example, if you have a reaction A and you add it to 2 of reaction B to get reaction C (A+2B = C), with Ka, Kb, and Kc being the equilibrium constants of each reaction, you would find Kc = Ka * (Kb^2).
