Inert gas

[Alen Huang 2G]

If an inert gas is added why do the equilibrium partial pressures not change?

[HannahRobinson3L]

Adding an inert gas into a gas-phase equilibrium does not result in a shift, because this doesn't change the volume of the system. There will be no effect on the concentrations or the partial pressures of reactants or products, because it is not a part of the overall reaction. But, I think the total pressure of the system will change.

[rachelhchem1I]

I believe it also has to do with the fact that the inert gasses are non-reactive, and therefore does not change partial pressures

[Anh Trinh 1J]

When adding inert gas, the pressure is changing but the volume stays the same. Moles of reactant, product, and volume are constant so there is no change in Reactants and Products concentration, and overall no effect on reaction when adding adding inert gas.

[Austin Aldujaili 2D]

Changing the pressure of an equilibrium reaction only affects the direction of the reaction because it changes the volume of the reactants/products. By adding an inert gas, you are increasing the pressure however you are not changing the volumes of your molecules and therefore not affecting the direction of the reaction.

Hi! When you're thinking about the effect of pressure on a system, you need to focus on the volume. When an inert gas is added, it doesn't change the volume. It's non-reactive and doesn't affect the concentrations of the molecules in the system.

An inert gas doesn't react so the partial pressures of the reactants and products don't change.

[Crystal Pan 2G]

Inert gases are not reactive, therefore they would not "shift" the equilibrium.

[Sean Wang 1F]

Inert gasses do not affect equilibrium partial pressures because they are non-reactive and therefore not affecting the volume.

[Sharon Kim 2A]

Adding inert gas will not change anything. The moles of reactant & product and volume remains constant. Consider it to be negligible.

[Violet Kwan 3H]

Adding an inert gas will not change equilibrium because it is non-reactive. So, inert gases do not change the partial pressures of the other gases.

[Colin Juett 2F]

Partial pressure is basically the pressure of one gas in a system. Therefore the inert gas would increase the total pressure of the system, but no the partial pressure of any of the gases.

[Edison Tham 3D]

Since inert gases do not react, adding in inert gases will not cause an increase in pressure in the actual products or reactants of the reaction.

[Vanshika Bhushan 1A]

The addition of a non-reactive gas does not change the partial pressures of the other gases in the container.

[Selena Quispe 2I]

Adding an inert gas increases the total pressure but has no effect on the volume and if there is no effect on the volume then there will be no effect on the concentration and will have no effect on the reaction.

[Talia Dini - 3I]

An inert gas will not change the equilibrium partial pressures because they are not reactive and will not have an effect on the volume. Hope this helps!

[Danielle DIS2L]

Inert gases do not affect the reaction because they do not react. Thus, not having an effect on volume.

[Brianna Chen 3F]

Inert gases increase the pressure of the overall reaction but do not affect the volume which is why it does not affect the concentrations of the reaction. In addition, inert gases refer to noble gases which are exceptionally stable and do not react.

[Joshua_Chan_3K]

Partial pressures would not change because partial pressure is due to the pressure from that specific gas. Since total pressure would increase, that is the partial pressure of the new gas.

[Jack Kettering 3D]

Inert gases do not react and therefore are not involved in the equilibrium reaction so the partial pressures of both the products and reactants do not change.

[Anastasia Yulo 1C]

Because inert gases are non-reactive, the partial pressures do not change when an inert gas is added to a system.

[Jack_Pearce_2H]

Shifts in equilibrium ultimately result from changes in the concentrations of the products or reactants. Because the reaction does not have a noble gas in its products or reactants and the volume of the chamber is not changing, the equilibrium concentrations of the products and reactants will remain the same.

[DPatel_2L]

The gas does not react so the partial pressures do change.

[Muskaan Abdul-Sattar]

Inert gases do not react, so it does not cause a shift in the equilibrium of a system.

[Katelynn Shaheen 2C]

Inert gases do not affect the volume because they are not reactive.

[Amy Jordan 2A]

Hi, equilibrium partial pressures do not change when you add an inert gas because the gas doesn't react with the reactants or the products of the chemical reaction, so they are not changed.
