what are the two main types of equilibria?
homogeneous
heterogeneous
what is a homogenous equilibrium?
contains equilibrium species that all have the same state or phase
what is heterogenous equilibrium?
contains equilibrium species that have different states or phases
what happens in heterogenous equilibrium relating to the Kc expression?
concentration of solids and liquids are constant so solids and liquids are omitted from the Kc expression
Kc only includes species that are gas or aq
