### Ideal gas law and reverse reactions

Does the ideal gas law still follow the general rule of reverse reactions wherein the equilibrium constant for an equilibrium written in one direction is the reciprocal of the equilibrium in the opposite direction since the ideal gas law is a bit more complex (accounting for the differences of stoichiometric coefficients)?

I believe so. If the forward reaction has an equilibrium constant Kp, then the reverse should have equilibrium constant 1/Kp

I'm pretty sure it does still follow this rule because that is a rule that we can generally follow in math so I would assume it also applies in this case.

The Kp/Kc for the reverse reaction would be Kp^1/Kc^-1 or 1/Kp or 1/Kc.
I'm sure this applies to Kp just as it does to Kc.

I believe it would! Logically it makes a lot of sense

I believe it does follow the rule!
