Pressure
Can someone explain the significance of pressure when discussing equilibrium constants? For example, how would adding an inert gas to a system at equilibrium change anything?

Re: Pressure [ENDORSED]
Adding an inert gas has no effect on the equilibrium concentration so it does not change the constant.

Re: Pressure
If the pressure of a reaction vessel is increased by adding an inert gas, then moles of reactant, product, and volume are constant. Therefore, there is no change in the reactant and product concentration and no effect on the reaction. Remember that an inert gas does not undergo chemical reactions under a set of given conditions. Therefore, if the moles of reactant, product, and volume remain constant then the composition of the reaction is the same and the K remains constant.
