Kp

Is Kp only used when dealing with gases?

Kp is meant to be used when dealing with the partial pressures of various gases, and Kc is meant to be used for concentrations.

Yes, Kp is only used with gases

Kp is used when dealing with gases, it is the equilibrium constant calculated from the partial pressures.

K is the general equilibrium constant while Kp refers to the equilibrium constant when using partial pressures.

KP is used to deal with the partial pressures of an equation at equilibrium, (P=Pressure). Since, as explained in lecture, you can't compress solids and it takes an absurd amount of energy to compress liquids a small amount, their affect on the pressure of a reaction container are taken to be negligible. Therefore, you should use KP only with gases.

Kp is only used for gases, while Kc is used for concentrations. If needed, you can convert individual species from concentration to atm through PV=nRT
