Sample WACE Year 12 Chemistry questions

These sample questions are visible on the page before login. They show WACE Year 12 Chemistry titration curves, equilibrium shifts, electrochemical cells, organic reactions, spectra, and kinetic data with diagrams, tables, curves, and spectra before opening the demo.

WACE Year 12 Chemistry Analytical titration hard titration curve

1. A titration curve shows a sharp endpoint near 21.20 mL. Which titre should be used in the final calculation?

Choices

A concordant titre near 21.20 mL
Only the rough titre
A random first reading
The mass-spectrum base peak

Explanation:

Reliable titration calculations use concordant titres close to the endpoint rather than the rough run alone.

WACE Year 12 Chemistry Equilibrium hard equilibrium diagram

2. For 2SO2(g) + O2(g) <-> 2SO3(g), pressure is increased. Which side is favoured by the lower number of gas moles?

Choices

SO3
SO2 and O2
No side
Only oxygen

Explanation:

The product side has 2 mol of gas compared with 3 mol on the reactant side, so higher pressure favours products.

WACE Year 12 Chemistry Redox hard electrochemical cell

3. An Fe/Cu galvanic cell shows iron losing electrons. Which half-equation represents oxidation?

Choices

Fe(s) -> Fe2+ + 2e-
Cu2+ + 2e- -> Cu(s)
NaCl -> Na+ + Cl-
H2O -> H+ + OH-

Explanation:

Oxidation is loss of electrons, so iron forming Fe2+ and electrons is the oxidation half-equation.

WACE Year 12 Chemistry Organic synthesis hard organic pathway

4. A reaction scheme shows many ethene monomers joining to form poly(ethene). What type of reaction is this?

Choices

Addition polymerisation
Ester hydrolysis
Neutralisation
Combustion only

Explanation:

Ethene monomers add across their double bonds to make a polymer without forming a small molecule by-product.

WACE Year 12 Chemistry Spectroscopy hard mass spectrum

5. A mass spectrum for butan-1-ol includes a molecular ion at m/z 74. What does this peak represent?

Choices

The molecular ion
The solvent only
A pH indicator
The salt bridge

Explanation:

The molecular ion is the ionised whole molecule and gives the relative molecular mass.

WACE Year 12 Chemistry Acid equilibria hard titration curve

6. A weak-acid titration curve marks the half-equivalence point. What is true at this point?

Choices

pH = pKa
pH must be 14
No acid remains initially
The base peak is tallest

Explanation:

For a weak acid titration, the half-equivalence point has equal acid and conjugate base concentrations, so pH equals pKa.

For parents comparing WACE Year 12 Chemistry support

WACE Year 12 Chemistry practice should help students connect chemical reasoning to visible evidence: titration curves, equilibrium shifts, electrochemical cells, organic reactions, spectra, and kinetic data. These examples preview that visual reasoning before the no-login Chemistry demo.
