TOUPADAKIS Lecture 12 Chapter 15 What are the Factors that Alter the Composition of an Equilibrium Mixture? When a chemical system at equilibrium is subjected to a change in: concentration of one or more reacting species or pressure/volume or temperature , the system shifts in the direction that reduces the stress. If given sufficient time, a new state of equilibrium is established. Le Châtellier’s Principle

TOUPADAKIS Lecture 12 Chapter 15 Altering an Equilibrium Mixture: Changes in Concentration At a given temperature, adding or removing reactants or products changes the value of Q . It does not change the value of the equilibrium constant K . A change in concentration only shifts the position of the equilibrium. In other words a new equilibrium state is reestablished with the components of the system being now in different
