Shifts in EQUILIBRIUM : Concentration

• If concentration of one species changes,

concentrations of other species CHANGES

to keep the value of K the same (at constant T)

• no change in K - only position of equilibrium changes.

ADDING REACTANTS

- equilibrium shifts to PRODUCTS

ADDING PRODUCTS

- equilibrium shifts to REACTANTS

REMOVING PRODUCTS

- often used to DRIVE REACTION TO COMPLETION

- GAS-FORMING; PRECIPITATION
