Equilibrium

Learning outcomes - after studying this topic, you should be able to:
  • explain what reactions are spontaneous and under what conditions
  • explain the dynamic nature of equilibrium processes
  • write the equilibrium constant for any reaction or process
  • use initial, change, equilibrium (ICE) tables
  • calculate the value of the equilibrium constant for a reverse reaction from its value for a forward reaction, and if the stoichiometry is changed
  • calculate the equilibrium constant for a reaction obtained by combining two other reactions
  • explain the difference between the equilibrium constant, K, and the reaction quotient, Q
  • write down the reaction quotient and use it to predict the direction of change
  • use Le Chatelier's principle to predict the response of a system at equilibrium to changes in temperature, pressure and composition
  • explain how catalysts effect chemical reactions without changing the equilibrium concentrations
  • relate the equilibrium constant, K, to the change in the Gibbs free energy
