19.1 The equilibrium constant Kc

• The units of Kc depend on the number of concentration terms on the top and bottom of the Kc expression
• A homogenous equilibrium contains equilibrium species that all have the same state
• A heterogenous equilibrium contains equilibrium species that have different states
• Kc only includes species that are gaseous or aqueous because their concentrations can change
• To calculate equilibrium amounts, use a MICE table
