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

• Explain the overall observations about equilibrium in terms of the
  collision theory

• 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

• The Haber Process
