Reaction Quotient

Postby AnnaTong1E » Sat Nov 12, 2016 4:25 pm

Are solids and liquids not included in the reaction quotient expression?
I know they are not included in the equilibrium constant calculation but I don't know if it applies to reaction quotients as well.

Thanks!

Remember in class I said the expression for the equilibrium constant, K, and the reaction quotient, Q, are identical.
Therefore solids and liquids not included in both.

What about aqueous solutions?

aqueous species are included in both Q and K as well

Pure solids and liquids are not included in the reaction quotient and K because their concentrations do not change throughout the reaction. Gases and aqueous solutions are the only ones that are included in calculations.
