What can the size of the equilibrium constant, Kc, tell us about the composition of the equilibrium mixture?
If Kc is much greater than 1, products predominate.
If Kc is much less than 1, reactants predominate.

What species are included in the Kc expression for a heterogeneous equilibrium mixture?
Only gaseous or aqueous species are incuded.
The concentrations of solids and liquids are essentially constant so they are omitted from the Kc expression.

All species are included.

What is the difference between a homogeneous equilibrium and a heterogeneous equilibrium?
A homoegeneous equilibrium contains equilibrium species that all have the same state or phase.
A heterogeneous equilibrium contains equilibrium species that have different states or phases.
