AQA GCSE Chemistry 8462/2H 2026: What Is Paper 2?
AQA GCSE Chemistry 8462/2H is the Higher Tier Paper 2 exam. It tests the second half of the GCSE Chemistry course, including rates, organic chemistry, chemical analysis, using resources and environmental chemistry.
Students searching for AQA Chemistry Paper 2 predictions, AQA GCSE Chemistry predicted topics 2026, 8462/2H predicted paper, AQA Chemistry practice paper or AQA GCSE Chemistry revision paper usually want to know which areas are worth prioritising before the exam.
The safest strategy is to revise the full specification. However, a focused Paper 2 predicted paper can help students practise the types of questions that are likely to test common weak spots, especially longer explanation questions, practical skills and application questions.
AQA GCSE Chemistry Paper 2 Predicted Topics for 2026
Based on this AQA GCSE Chemistry 8462/2H 2026 predicted paper, students should give particular attention to the following predicted topic areas.
1. Rates of Reaction, Activation Energy and Collision Theory
Rates of reaction are a strong AQA GCSE Chemistry Paper 2 predicted topic. Students should be able to explain reactions using collision theory and activation energy.
Revise:
Activation energy
Successful collisions
Collision frequency
Effect of temperature on particle speed
More particles having energy greater than or equal to activation energy
Energy profile diagrams
This is a useful AQA Chemistry 8462/2H predicted topic because students often lose marks by saying only “particles move faster” without explaining successful collisions.
2. Catalysts and Reaction Pathways
Catalysts are closely linked to rates of reaction and energy profiles. The predicted paper includes catalyst questions, so students should revise both the definition and the explanation.
Revise:
Catalysts providing an alternative reaction pathway
Lower activation energy
More successful collisions
Faster reaction rate
Industrial catalyst examples
Iron in the Haber process
Nickel in hydrogenation
Platinum in catalytic converters
This is a strong AQA GCSE Chemistry Paper 2 prediction because catalyst questions can be short but require precise wording.
3. Crude Oil and Fractional Distillation
Crude oil and fractional distillation are important Paper 2 topics. The predicted paper includes a fractionating tower diagram and questions on how fractions separate.
Students should revise:
Crude oil as a mixture of hydrocarbons
Different boiling points
Temperature gradient in the fractionating column
Hotter at the bottom and cooler at the top
Condensation at different heights
Shorter alkanes having lower boiling points
Longer alkanes being more viscous
This is a useful AQA Chemistry Paper 2 practice paper topic because diagrams are common and students must link boiling point to separation.
4. Complete and Incomplete Combustion
Combustion questions are common in GCSE Chemistry and can test equations, products and oxygen supply.
Revise:
Complete combustion producing carbon dioxide and water
Balanced combustion equations
Combustion of propane
Incomplete combustion with limited oxygen
Carbon monoxide
Carbon / soot
This is a strong predicted topic because balancing hydrocarbon equations is an easy place to gain marks if the method is secure.
5. Cracking and Alkanes
Cracking is an important GCSE Chemistry Paper 2 topic because it links crude oil, demand and organic products.
Students should revise:
Longer alkanes being broken into shorter alkanes
Shorter alkanes being in higher demand
Production of alkenes
Alkenes used to make polymers and chemicals
Shorter alkanes having lower boiling points
This is a useful AQA GCSE Chemistry prediction because it often appears as a short explanation question.

Students should revise:
Amine group –NH₂
Carboxylic acid group –COOH
Condensation reaction
Removal of H and OH to form water
Peptide bond –CO–NH–
Proteins made from amino acid monomers
Starch made from glucose monomers
Peptide bonds versus glycosidic bonds
This is a useful 8462/2H predicted topic because students can lose marks if they describe the reaction vaguely instead of identifying the bond and water formation.
8. Chromatography and Rf Values
Chromatography is a major Paper 2 practical topic. The predicted paper includes paper chromatography for metal ions, baseline technique and Rf calculations.
Revise:
Drawing the baseline in pencil
Ink dissolving in solvent
Keeping the solvent below the baseline
Using small concentrated spots
Solvent front
Rf value formula
How changing solvent changes Rf values
Measuring with a ruler in mm
Avoiding contamination from fingers
This is one of the strongest AQA GCSE Chemistry Paper 2 predicted topics because chromatography combines practical method, calculation and explanation.
9. Metal Ions and Precipitate Tests
The predicted paper includes metal ions and coloured precipitates after adding sodium hydroxide.
Students should revise:
Copper(II) ions forming blue precipitates
Iron(II) ions forming green precipitates
Iron(III) ions forming brown precipitates
Formula Fe(OH)₂
Formula Fe(OH)₃
Different ion charges affecting precipitate colour
This is a useful revision area because students must know both observations and formulae.
10. Alkenes and Addition Reactions
Alkenes are a high-value organic chemistry topic for AQA GCSE Chemistry Paper 2.
Revise:
Alkenes as unsaturated hydrocarbons
C=C double bond

Students should revise:
Fertilisers providing nutrients for plant growth
Increased crop yield
Ammonium nitrate made from ammonia and nitric acid
Nitrogen from air
Hydrogen from natural gas and steam
Reversible reaction between nitrogen and hydrogen
High temperature increasing rate
High pressure increasing ammonia yield
Iron catalyst increasing rate without changing yield
Compromise temperature and pressure
This is one of the most important AQA GCSE Chemistry Higher Paper 2 predicted topics because the Haber process can appear as a six-mark explanation.

Potable water and desalination are key “using resources” topics.
Revise:
Fresh water treatment
Filtration
Sterilisation
Low microbe levels to prevent disease
Desalination of sea water
High energy cost of distillation
Reverse osmosis requiring pressure
Ultraviolet light and ozone for sterilisation
Percentage calculations from water-source data
This is a useful AQA Chemistry revision paper topic because it combines recall, explanation and calculations.
