Equilibrium Calculations

The equilibrium constant of a reaction in the reverse reaction is

the reciprocal of the equilibrium constant of the forward reaction.

The equilibrium constant of a reaction that has been multiplied by a number is

the equilibrium constant raised to a power that is equal to that number.

Types of equilibrium calculations

Calculation of an equilibrium constant

Calculation of missing equilibrium concentration or partial pressure

Calculation of equilibrium concentrations (or partial pressures) from initial concentrations (or partial pressures)

The equilibrium constant for a net reaction made up of two or more steps is

the product of the equilibrium constants for the individual steps
