Sample QCE Year 12 Chemistry questions

These sample questions are visible on the page before login. They show QCE 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.

QCE Year 12 Chemistry Titration hard titration curve

1. A vinegar aliquot reaches endpoint after 25.00 mL of 0.100 mol L^-1 NaOH. How many moles of NaOH were delivered?

Choices

0.00250 mol
2.50 mol
0.250 mol
25.0 mol

Explanation:

n = cV with volume in litres: 0.100 x 0.02500 = 0.00250 mol.

QCE Year 12 Chemistry Equilibrium hard equilibrium diagram

2. The forward reaction N2 + 3H2 <-> 2NH3 is exothermic. If temperature is lowered, which side is favoured?

Choices

NH3
N2 and H2
No side
Only the catalyst

Explanation:

Lowering temperature favours the exothermic direction, producing more ammonia.

QCE Year 12 Chemistry Electrochemistry hard electrochemical cell

3. A Mg/Cu galvanic cell shows magnesium atoms forming Mg2+ ions. Which electrode is being oxidised?

Choices

Magnesium
Copper
The salt bridge
The beaker wall

Explanation:

Magnesium loses electrons to form Mg2+, so it is oxidised at the anode.

QCE Year 12 Chemistry Organic materials hard organic pathway

4. An organic reaction diagram shows ethene reacting with steam in an addition reaction. What product is formed?

Choices

Ethanol
Ethanoic acid
Ethyl ethanoate
Polyethene

Explanation:

Hydration adds H and OH across the C=C bond in ethene to form ethanol.

QCE Year 12 Chemistry Analytical chemistry hard mass spectrum

5. A mass spectrum for a compound containing chlorine has M and M+2 peaks in about a 3:1 ratio. What does this pattern suggest?

Choices

Chlorine isotopes
No isotopes are present
Only hydrogen is present
The sample is pure water

Explanation:

Chlorine commonly gives molecular-ion peaks two mass units apart in about a 3:1 ratio.

QCE Year 12 Chemistry Kinetics hard rate graph

6. A graph shows concentration halving from 0.60 to 0.30 mol L^-1 in 10 min and from 0.30 to 0.15 mol L^-1 in the next 10 min. What pattern is shown?

Choices

A constant half-life
Zero reaction rate
A pH endpoint
A mass-spectrum base peak

Explanation:

Equal time intervals for successive halvings indicate a constant half-life.

For parents comparing QCE Year 12 Chemistry support

QCE 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.
