P(k) and P(q)

[Simon Dionson 4I]

If we were calculating a reaction with multiple phases (i.e. solid, liquid, aqueous, gas), will calculating P(q) and P(k) only deal with the gases?

[Asha Agarwal 1E]

When calculating K(p) and Q(p), solids and liquids(solvents) are not included but both aqueous species and gases are included.

[Ashley Tran 2I]

To clarify for both Q (initial conditions) and K (equilibrium conditions): when the compounds are gases use P for partial pressure and when the compounds are in aqueous state use the concentration (brackets). Disregard compounds in solid or liquid phase. Don't use partial pressure and concentration in the same Q/K expression... I don't think we're ever given problems like that.
