Chemical Equilibrium
PRINCIPAL FACTS AND IDEAS
1. The principles of thermodynamics determine the state of chemical
equilibrium for any reaction.
2. The equilibrium constant expression of elementary chemistry is equal to a
constant at constant temperature when it is expressed in terms of
activities.
3. The principle of Le Châtelier can predict how a chemical system at
equilibrium responds to changes in temperature, pressure, or amounts of
substances.
4. The coupling of biochemical reactions can be understood through
thermodynamics and the use of postulated mechanisms.
