Inert Gas

Postby TanveerDhaliwal3G » Mon Jan 20, 2020 1:07 pm

Why does adding an inert gas and therefor increasing the pressure not have an effect?

When talking about the effect of inert gases on a reaction at equilibrium, we are more focused on the fact that it is extremely stable and thus does not react. The inert gas wouldn’t interact significantly with the other reactants/products in the reaction and this has no net effect on the direction of the reaction. In his learning module, however, Lavelle did explain that a reaction might slow down with the addition of an inert has because the molecules might interfere with the interactions between the molecules of the other reactants/products. However, this slowing down is not necessarily extremely significant and therefore isn’t addressed.

Although adding an inert gas affects the total volume of the reaction, they do not interact with anything, thus causing there to be no change in concentration.

I thought the whole point was that adding a inert gas doesn't affect the volume of the container, which was why it has no affect on concentration. Remember that concentration is moles/volume.

Inert gases don't interact with anything, which indicates that the initial concentrations remain the same after the addition of the inert gas.

Inert gas is usually noble gases or very stable gases which are not likely to react with the contents in the reaction vessel. Although by adding inert gas, it is increasing the pressure of the reaction vessel, the gas being added isn’t going to effect the reaction but just exist around it instead.

Similarly, why would adding a halogen be special in shifting/not shifting a reaction a certain way?
