Thank you!! I didn't realize it was just another word for "noble". Thought it was a completely different concept lol
In the context of equilibrium reactions, the insertion of inert gases may increase the overall pressure of the reaction vessel, but it has no effect on the main reactant and product concentrations which means K does not change. Just to add on
An inert gas does not affect the partial pressures of the components of a reaction at equilibrium (however, adding an inert gas may change the total pressure of a container). This is because the inert gas does not interact with any of the species of the reaction.
An inert gas is a gas that typically does not react with any other molecules. These are gases in the last column of the periodic table and don't want to give off or gain an electron since their valence shell is already full.
An inert gas would be one that does not affect the outcome of the reaction. For instance, if you added Cl2 to a reaction that does not involve Cl2 and will not react with it, the same exact concentration of CL2 would be in the reactants as well as the products, only changing the volume and thus the pressure, not the concentrations.
Inert gases are usually noble gases that typically don't have an effect on the reaction taking place. As Dr. Lavelle said in lecture, adding an inert gas changes the pressure but will not change the concentrations of the reactants and therefore will have no effect on K.
Inert gases is another name for the Noble gases and these are essentially the elements on the last column of the periodic table. Since these gases have a complete octet, they are unreactive with other molecules in a reaction. When working out problems with partial pressures, these gases do no affect the partial pressures of the components but they could affect the total pressure.
