increasing/decreasing a solid/liquid

Postby Sofia Lombardo 2C » Sun Jan 17, 2021 2:55 pm

I know that if there is an increase/decrease in concentration, pressure, and temperature the equilibrium will adjust to minimize the effects of these changes. Does this still apply if there is an increase/decrease in the concentration of a solid or liquid? Or does the reaction not change?

The reaction does not change if a solid or liquid is increased/decreased. Since we don't include solids/liquids when determining the equilibrium constant, adjusting the amount of solids and liquids cannot affect the reaction's equilibrium state.

We do not include liquids nor solids in the equilibrium expression so the amount to solid or liquid won't cause a change in the equilibrium

Solids and liquids aren't included in these changes because their effects are very small and are negligible in most cases

A solid doesn't have a concentration, so it would not affect the equilibrium concentrations. Liquid would not would not have an effect due to the reasons described above.

No, there is no change when the concentration of a liquid or solid is modified at equilibrium.

You do not include solids and liquids into your equilibrium equation. Also, someone correct me if I am wrong, but the temperature is the only thing that truly affects the k value.
