### Inert Gas

What is an "inert gas" and what makes certain gases inert? Professor Lavelle used this term in lecture and I'm not familiar with it

### Re: Inert Gas

Basically, an inert gas is any of the noble gases. It's considered "inert" because most of the noble gases do not react.

Thank you!! I didn't realize it was just another word for "noble". Thought it was a completely different concept lol

### Re: Inert Gas

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

### Re: Inert Gas

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.

### Re: Inert Gas

An Inert gas or a noble gas does not react with many substances and therefore would not affect chemical reactions. It would then not affect the concentrations of the reactants and products.

### Re: Inert Gas

So we treat inert gases like water in an aqueous reaction?

### Re: Inert Gas

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.

### Re: Inert Gas

So does that mean that we don't include it in our calculation for finding Kp? Also in that case, why even add an inert gas at all?

### Re: Inert Gas

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.

### Re: Inert Gas

An inert gas is a non-reactive gas. In other words, they are noble gases.

### Re: Inert Gas

Noble/Inert gases are gases in group 18 of the periodic table and are usually unreactive in chemical reactions due to their full outer shell

### Re: Inert Gas

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.

I too was confused on what Dr. Lavelle meant by "inert gas", but it basically is just another word for noble gas. These gases are usually unreactive.

### Re: Inert Gas

An inert gas is the same as a noble gas. It's "inert" because it is unreactive and doesn't bond often.

### Re: Inert Gas

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.

### Re: Inert Gas

Since noble gases do not interact often with other chemicals, they are often called inert gases.

Inert gases are non-reactive gases, such as noble gases. Hope this helps!

Hi! Inert gases are noble gases.
