Kp to Kc

Postby Abigail Menchaca_1H » Sun Jan 26, 2020 7:06 pm

If H2O is a gas in Kp, would it be included in the Kc calculation since it's a gas?

Yes, because in this case water isn't in the pure liquid form.

Yeah it usually relies on the problem and if it gives you the calculations in concentration (mol.L) or pressure (bar, atm, etc..) You can calculate both Kp and Kc of water in its gaseous form.

yes, as long as H20 is not in pure liquid form.

Yeah
The only time you’d exclude h2o is if it were in liquid or solid form

Yes as long as it is in the form of a gas. Any gas or aqueous reactant or product can be included in solving for K.

yes unless it states that it's a pure liquid

Liquid water is not included in equilibrium concentration calculations.

Yes, unless it is a pure solid or gas.

Yes, because it is a gas and we include gases in Kc. (just depends on state given)
