Essential ideas:
- The position of equilibrium can be quantified by the equilibrium law. The equilibrium constant for a particular reaction only depends on the temperature.

17.1 Equilibrium and Gibbs free energy
|
|
Understandings:
The position of equilibrium corresponds to a maximum value of entropy and a minimum in the value of the Gibbs free energy. The Gibbs free energy change of a reaction and the equilibrium constant can both be used to measure the position of an equilibrium reaction and are related by the equation, ∆G° = −RT lnk Applications and skills: Relationship between ∆G and the equilibrium constant. Calculations using the equation ∆G° = −RT lnk |
