CHEM1101 - Resources for Week 11

Topics and Learning Outcomes

  • Entropy
    •  explain the thermodynamic concept of spontaneity
    •  define entropy as the tendency of energy to spread out in a spontaneous process
    •  predict the relative entropy of solids, liquids and gases and how entropy is affected by temperature, molecular size and complexity
    •  define and use the Second Law of Thermodynamics
    •  relate the entropy change of the universe to the Gibbs free energy
    •  use Gibbs free energy to predict spontaneous and non-spontaneous processes
  • Equilibrium
    •  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
  • Equilibrium and Thermochemistry in Industrial Processes
    •  explain the main processes used industrially to extract metals from their ores
    •  use Ellingham diagrams to predict which metals can be extracted using coke at different temperatures
    •  discuss the role of the chemical industry in the modern world and Australia with particular regard to the Top Ten chemicals
    •  outline the thermodynamic principles behind the industrially optimized routes to sulfuric acid and ammonia
