Do we include H2O in the gas phase? I know we don't include it in the liquid phase but I am unsure about gas.

Gases are included in equilibrium constant equations.

Yes, you would include gases in equilibrium expressions, but you wouldn't include solids or liquids.

Yes. All gases should be included in the equilibrium constant.

I believe that gases are always included because they contribute to partial pressures, which are important in calculating K if the equilibrium is all gaseous.

I believe only gases are included when finding equilibrium constants.
Also, can someone explain how to ask a question on Chem Community? I cannot figure out how to. Thanks

You have to go to a certain topic and then click on new topic in the top left corner. Name the subject something that people can recognize and type your question in the main text box.

Yes, gases are included in the gas phase. H20 in the liquid phase is not used because they do not affect the reactant amount at equilibrium.

Yes, you would use H2O because you include all gases in the equation.
