Solids and Liquids?

[Stacey Phan 2I]

For Le Chatlier, changing the amount of gases and aqueous components affects the reaction but not solids or liquids?

[rachelhchem1I]

Hi - only gases apply for this law! So make sure to check the phases in the reaction you are looking at

[Aliya 1H]

Yea, only the gases count for this. A good example question would be focus 5 number 5.61, which has you say what direction in which the rxn will shift for a variety of different changes.

[AmyHo2K]

Hi, I believe that only gases work for this law.

[Katelynn Shaheen 2C]

Only gases would apply to this.

[Lakshmi Davuluri 1E]

I don't think changing the amount of aqueous solutions applies here, just gases.

[ellenulitsky Dis 1I]

I had this same question too and was told it's only gases, not aqueous solutions too.

[Serena Song 1A]

Only gases apply for Le Chatelier. For example, if pressure increased, only the concentration of gases would be affected since they can be compressed unlike solids, liquids, and gases.

[Saumya Tawakley 1E]

Yes, only gases apply to this law since liquids and solids generally experience almost no changes in concentration as a result of changes in pressure, volume, etc.

[Hannah Biju 1E]

Yep, Le Chatelier's principle only applies to gases because that is the only state that can really be compressed or expanded.

[Michelle Nguyen 3F]

Yes, it only applies to gases because solids and liquids do not have a significant enough change in concentration or pressure to be measured for the equilibrium in general

[Sreeram Kurada 3H]

Yeah only gases apply for Le Chatelier's principle.

[VSU_3F]

Yes, only gases! Solids are not considered to have a concentration, and liquids are always assumed to be in extremely high volumes, so they don't tend to shift a reaction either way.

[Joshua_Chan_3K]

People are saying only gases apply but I still think aqueous components do as well. If you remove some of an aqueous reactant, the reaction would shift towards the reactants. If anyone has an answer to this I would appreciate it as well.

[Moura Girgis 1F]

That's right, Le Chatelier's Principle only applies to gases.

[Diana Aguilar 3H]

Yes, like many others have stated, only gases apply to Le Chatelier's Priniciple

[Queena Chu 3E]

Yes, only gases apply to this principle.

[Bai Rong Lin 2K]

It would only affect the gases.

[Shana Patel 1C]

Le Chatelier's Principle only applies to gases. However this does not affect the solid and pure liquid systems since their active masses are always taken as unity.

[David Y]

For this law, only gases apply.

[Bryan Le 2K]

Only gases apply to this law! Make sure to check the reaction. I make this mistake a lot on exams and practice problems.

[George Hernandez 3I]

Gases are applied to this law only

[Ismar Zamora]

Only gases!

[Nishka Vipul 1J]

Yes, only gases are considered when applying Le Chatelier's principle!

[Mandy Mg 2J]

Yes! Changing components of solids and liquids would not affect its concentration in equilibrium so they are not affected by Le Chatelier's Principle.

[Caitlin_Doak_2H]

Yes, only gases!

[Vivek Chotai 2C]

People are saying only gases apply but I still think aqueous components do as well. If you remove some of an aqueous reactant, the reaction would shift towards the reactants. If anyone has an answer to this I would appreciate it as well.

I agree. I am not sure why people are saying this only applies to gases. We know changing the concentration of an aqueous solution (we even include them in the equilibrium constant) will make the system adjust to go back to equilibrium. It would have to in order to make the product to reactant ratio the same.
