K

[Sophia Dinh 1D]

How do you know what to include and exclude when calculating K?

[Connie Chen 1E]

You generally include gases and aqueous solutions and exclude solids and liquids in the calculation of K. This is because solids and liquids are usually present in excess so a change to its concentration results in a negligible change.

[AKhanna_3H]

Only include gases and aqueous solutions. Disregard solids and liquids.

[Jarrett Peyrefitte 2K]

Solids and liquids are always excluded regarding K and Q.

[205405339]

when calculating K look for (aq) or (g) and exclude (s) or (l)

[Jaci Glassick 2G]

Solids and liquids are excluded when calculating Q and K. Gases and aqueous particles are included.

[Kallista McCarty 1C]

You use gaseous and aqueous! You don't put in solids or liquids

[J_CHEN 4I]

For a gas (g) and solutes in solutions (aq), their activity is included for solving for K. For pure solids (s) and liquids (l), their activities are 1.

[KHowe_1D]

You include gases and aqueous solutions but exclude liquids, such as water, and solids.

[Hannah Pham]

To calculate K, use gases and aqueous solutions but not solids or liquids.

[Kate Osborne 1H]

use anything that has a concentration or a pressure (so only aqueous things or gases!)

[sarahartzell1A]

Exclude pure solids and liquids!

[BCaballero_4F]

You would include whatever has (g) and (aq) from the reaction, and not solids or liquids
