VCE Chemistry practice exams and worked solutions
Chemistry marks are won on precision: a balanced equation with states, a calculation carried through with units, an explanation that names the bond rather than gesturing at it. These papers ask for all three.
What the course asks of you
- Bonding and structure
- Why a substance melts where it does, argued from the bonding rather than recalled.
- Stoichiometry
- Moles, limiting reagents and concentration, carried through to a sensible number of figures.
- Energy and rates
- Enthalpy, Hess's law, activation energy, and what actually speeds a reaction up.
- Redox and electrochemistry
- Half-equations, cell potentials, and predicting whether a reaction will go.
