Solids and liquids

Postby Jarrett Peyrefitte 2K » Thu Jan 16, 2020 1:30 pm

Why do we omit solids and liquids when writing for Kc and Kp?

Solids and liquids don't affect the value of K, so we leave them out.

Solids don't react in solution and liquids don't dissociate enough to change the reaction, so they don't count in the k equations

Solids do not have concentration or pressure, which is why they are left out of K expressions.
Liquids are usually solvents and have a very insignificant change in concentration, which is why they are not included in K expressions either.
