 Chemistry Units 3&4

What is it and why should I do it?

Chemistry is a subject for students who are interested in the chemical processes that occur on Earth and beyond. Topics covered include Energy, its production and use; carbon-based compounds, pathway of production and investigation using current analytical techniques; industrial Chemistry, considering rates of reactions and equilibrium constraints the chemistry of biological compounds. The course builds on work done in Unit 1 &2 Chemistry but is mainly new content.

How much homework/study will I have?

All Unit 3 and 4 subjects require 3 – 5 hours of study per week.

Chapter review questions and worksheets will need to be completed for homework. It is expected that students will review notes competed in class, each night after class, and more homework will be required studying for assessments.

What contributes to my study score?

SAC 5 – Extended experimental (Research based on combustion of fuels)                                              8%

Exam – 2.5 hours external assessment                                                                                                       60%


How do I Satisfactorily Complete the unit?


To pass any VCE subject you need to demonstrate that you have met the Outcomes. In Chemistry you meet the Outcomes primarily through completion of coursework, participation in class discussion, practical work and SACs.


Unit 3

AOS 1 Outcome 1

Compare fuels quantitatively with reference to combustion products and energy outputs, apply knowledge of the electrochemical series to design, construct and test galvanic cells, and evaluate energy resources based on energy efficiency, renewability and environmental impact.

AOS 2 Outcome 2

Apply rate and equilibrium principles to predict how the rate and extent of reactions can be optimised, and explain how electrolysis is involved in the production of chemicals and in the recharging of batteries.

Unit 4

AOS 1 Outcome 1

Compare the general structures and reactions of the major organic families of compounds, deduce structures of organic compounds using instrumental analysis data, and design reaction pathways for the synthesis of organic molecules.

AOS 2 Outcome 2

Distinguish between the chemical structures of key food molecules, analyse the chemical reactions involved in the metabolism of the major components of food including the role of enzymes, and calculate the energy content of food using calorimetry.

AOS 3 Outcome 3

Design and undertake a practical investigation related to energy and /or food, and present methodologies, findings and conclusion in a scientific poster.
