The Effect of Changing Concentration on the Position of Equilibrium

AQA AS-level ChemistryEquilibriaLesson 18 of 20

The equilibrium constant does not change unless the temperature changes.

If the equilibrium is disturbed by changing the concentration the position of equilibrium will shift so that a new equilibrium will be set up
