Finding K without aq

Postby WYacob_2C » Wed Jan 08, 2020 5:56 pm

In class, we discussed finding the equilibrium constant while ignoring species in a reaction at the solid or liquid phase. If all species in a chemical reaction are solids/liquids what would the value of K be? Would there be a value of K? Thank you in advance.

I think the K would just be 1. On a ChemLibre website it just says that solids and liquids are essentially just 1, so for a reaction with all solids and liquids I assume 1 makes the most sense.

Since the K values are based on the species that are aqueous and in your scenario all of the species are solid and/or liquid, the "imaginary coefficient" 1 that is usually ignored due the use of concentrations (or partial pressures) values would be the K value. I believe that Professor Lavelle mentioned this in class today.

The value of K would be 1. However, it is very rare.

K would be 1 since the activities of solids and liquids are all 1.
