Topic 17 Equilibrium

17.1 Solve homogeneous equilibrium problems using the expression for Kc.
Understandings:
Le Châtelier’s principle for changes in concentration can be explained by the equilibrium law.
Applications and skills:
Solution of homogeneous equilibrium problems using the expression for Kc.


This video covers how to calculate the equilibrium concentrations of reactants and products when given the equilibrium constant and the initial concentrations. 

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
