● 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)[/cs_text][/cs_column][/cs_row][/cs_section][cs_section parallax=”false” separator_top_type=”none” separator_top_height=”50px” separator_top_angle_point=”50″ separator_bottom_type=”none” separator_bottom_height=”50px” separator_bottom_angle_point=”50″ style=”margin: 0px;padding: 45px 0px;”][cs_row inner_container=”true” marginless_columns=”false” style=”margin: 0px auto;padding: 0px;”][cs_column fade=”false” fade_animation=”in” fade_animation_offset=”45px” fade_duration=”750″ type=”1/1″ style=”padding: 0px;”][cs_text]Extract from Chemistry Stage 6 Syllabus © 2017 NSW Education Standards Authority (NESA)[/cs_text][/cs_column][/cs_row][/cs_section][/cs_content]
