K vs Kc

Postby 205192823 » Tue Jan 21, 2020 12:00 am

When should you use K and Kc? It said whenever the calculations of an equilibrium constant from thermodynamic tables of data (standard Gibbs free energies of formation) it should use K and not Kc, why is this and what other instances would I have to keep this in mind?

Kc means that concentrations were used for the values when finding the equilibrium constant. K would vary depending on what form of values were used, for example Kp for partial pressures and Kc for concentrations.
