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
