Inert gas
What is the explanation behind why when inert gas is added and pressure increases, reactant product and volume still stay the same?

Re: Inert gas
Adding an inert gas affects pressure, but not the individual partial pressures of the gasses. So, the Kp remains constant, and the reaction isn't shifted.

Re: Inert gas
Reactant and Product concentrations will remain the same as volume does not change, therefore Kp is unchanged.

Re: Inert gas
The addition of inert gases does change the pressure of the system, but the volume remains the same. The number of reactants and products remains the same, therefore there is no reason for a q value to be calculated.
Re: Inert gas
why doesn't the individual partial pressure change and the pressure of the system does change?

Re: Inert gas
To clarify, by "inert gas", you guys are referring to mostly helium and the noble gasses right? These are inert gasses because they will not react due to their full valence shells?

Re: Inert gas
This is supposed to show that even though pressure was changed, the equilibrium didn't shift, thus showing that equilibrium doesn't shift in response to changes in pressure, but changes in concentration. In this case, there were no changes in moles or volume, so concentration didn't change.
