Module 5: Equilibrium

Inquiry Question 2: What factors affect equilibrium and how?

  • Investigate the effects of temperature, concentration, volume and/or
    pressure on a system at equilibrium and explain how Le Chatelier’s
    principle can be used to predict such effects, for example: Heating cobalt(II) chloride hydrate, interaction between nitrogen dioxide and dinitrogen tetroxide and iron(III) thiocyanate and varying concentration of ions
  • Examine how activation energy and heat of reaction affect the
    position of equilibrium

Inquiry Question 3: How activation energy and heat of reaction affect the
position of equilibrium

  • Deduce the equilibrium expression (in terms of K eq ) for
    homogeneous reactions occurring in solution
  • Perform calculations to find the value of K eq and concentrations of
    substances within an equilibrium system, and use these values to
    make predictions on the direction in which a reaction may proceed
  • Qualitatively analyse the effect of temperature on the value of K eq
  • Conduct an investigation to determine K eq of a chemical equilibrium system, for example: K eq of the iron(III) thiocyanate equilibrium
  • Explore the use of K eq for different types of chemical reactions, including but not limited to:
    • dissociation of ionic solutions
    • dissociation of acids and bases
