Le Chatelier's with Solids

Postby Ayesha Aslam-Mir 3C » Sat Jan 16, 2021 11:17 am

If you have a reaction where a solid and gas react to make a gas, would increasing the amount of solid cause the reaction to favor the products? Or would there be no change?

Adding more or taking away pure solids or pure liquids does not affect their concentrations because there's little change for pure solids and pure liquids in equilibrium reaction. Therefore Le Chatelier's principle does not apply to pure liquids or pure solids.

Solids and liquids are omitted from equilibrium equations, so you never have to consider their concentrations

Increasing the amount of solid or liquid will have no effect on the equilibrium reaction, so you can neglect those two when solving parts of an equilibrium reaction.

No, because solids don't really have concentration, so they have no impact on the K, and thus changing the amount of solid doesn't affect whether the reaction favors reactants or products. Hope this helps :)

Solid and liquids are omitted due to the fact that they do not have concentrations. Therefore, they would have no influence on the K and will not favor reactants or products.
