Can someone clarify the following for me? Are these the correct uses for Kc and Kp?
Kc = concentration of gases
Kp = partial pressures
Kc and Kp

Re: Kc and Kp
Kc is used for concentration in general, it applies to aqueous solutions and gases. Kp applies to partial pressures of gases.

Re: Kc and Kp
You are right with both Kc and Kp.
Kc is the equilibrium constant of the concentration of the aqueous solution.
Kp is the equilibrium constant of the partial pressure of the gas.
Kc is the equilibrium constant of the concentration of the aqueous solution.
Kp is the equilibrium constant of the partial pressure of the gas.
Re: Kc and Kp
Does Kc and Kp have to be in certain units or can we use any unit for concentration or pressure to get Kc or Kp?

Re: Kc and Kp
You use Kp for gases because it indicates partial pressure, since gases don’t really have a “concentration”. Kc is for concentrations of solids, liquids, and aqueous solutions.
