Inquiry question: How can the position of equilibrium be described and what does the equilibrium constant represent?
Students:
● deduce the equilibrium expression (in terms of Keq) for homogeneous reactions occurring in solution (ACSCH079, ACSCH096)
● perform calculations to find the value of Keq and concentrations of substances within an equilibrium system, and use these values to make predictions on the direction in which a reaction may proceed (ACSCH096)
● qualitatively analyse the effect of temperature on the value of Keq (ACSCH093)
● conduct an investigation to determine Keq of a chemical equilibrium system, for example:
– Keq of the iron(III) thiocyanate equilibrium (ACSCH096)
● explore the use of Keq for different types of chemical reactions, including but not limited to:
– dissociation of ionic solutions
– dissociation of acids and bases (ACSCH098, ACSCH099)
