The four Year 12 modules

Module 5 Equilibrium and Acid Reactions, Module 6 Acid/Base Reactions, Module 7 Organic Chemistry and Module 8 Applying Chemical Ideas. The exam gives them approximately equal weighting, Working Scientifically skills run through every module, and the Year 11 course is assumed knowledge.

The two sections of the paper

  • Section I, 20 marks: objective-response (multiple-choice) questions.
  • Section II, 80 marks: 20 to 25 items, which may contain parts. At least two items are worth 7 to 9 marks.
  • A NESA-approved calculator is allowed, and a formulae sheet, data sheet and periodic table are provided.

Which HSC this course is for

The Chemistry Stage 6 Syllabus (2017) is the current syllabus, examined in the 2026, 2027 and 2028 HSC. NESA's curriculum reform timeline lists the new Chemistry 11-12 syllabus as taught in schools from 2028 and first examined in the 2029 HSC, so this course follows the 2017 syllabus.

The table gives Keq at three temperatures for a gas reaction X(g) + Y(g) ⇌ Z(g). Which conclusion is supported?
Question 2
Solubility of four alcohols in water at 20 °C
AlcoholSolubility (g per 100 g water)
methanolmixes in all proportions
butan-1-ol7.4
hexan-1-ol0.59
octan-1-ol0.054
The table shows the solubility of four alcohols in water at 20 °C. Which statement best explains the trend?

Questions people ask

Which HSC does this syllabus cover?

The 2026, 2027 and 2028 HSC, so students sitting the HSC next year use this syllabus. NESA's timeline lists the new Chemistry syllabus as first examined in the 2029 HSC.

Is Year 11 Chemistry in the exam?

The exam is set on Modules 5 to 8, and the Year 11 course is assumed knowledge, so moles, stoichiometry, gas volumes and enthalpy can appear inside Year 12 questions.

Can I use a calculator?

Yes, a NESA-approved calculator, with the formulae sheet, data sheet and periodic table provided in the exam.
