Equilibrium constant

[Valeria Viera 1B]

How come pressure does not affect Kc? It does affect Kp right?

[Jaira_Murphy_2D]

Kc is just referring to calculating the eq of given concentrations and Kp refers to calculating the eq of given pressures.

[Angela Grant 1D]

Technically, it affects both since pressure and concentration are related by PV=nRT --> P=(concentration)RT <--> concentration=P/RT
But yes Kp is pressure and Kc is concentration

Kp is dealing with the pressure not essentially the concentration like Kc is

[Celeste 1I]

Just as a note Kp can only be used when talking about gases. Not sure if that helps. The partial pressure or concentration can be used depending on which is given.

[Yiting_Gong_4L]

Kp and Kc both give the equilibrium constant, but Kp is for partial pressure and Kc is for concentration.

[Laurence Tacderas 1K]

Partial pressures of the reactant and products affect Kp, not Kc. Changing the pressure by reducing the volume can affect both Kp and Kc.
