Define the term Chemical Equilibrium
Explain what is happening when a system is in equilibrium
Describe the Law of Mass Action
Write an Equilibrium Expression for a reaction.
Solve for the Reaction Quotient (Q) for a reaction using concentrations or partial pressures
Determine using the Equilibrium Constant (Kc or Kp) for a reaction if a reaction is at
equilibrium.
Define Homogeneous Equilibrium
Define heterogeneous Equilibrium
Explain how a solid or pure liquid is treated in an Equilibrium Expression
Describe how the Reaction Quotient is used to predict which way a reaction will shift to
obtain equilibrium.
Calculate Equilibrium concentrations and partial pressures.
Know what modifications can be done to systems with very small Equilibrium constants.
Use Le Chatlier’s Principle to determine the shift a reaction will undergo if a stress is applied
to the system at equilibrium.
