AQA GCSE Trilogy Chemistry 2h 2025 Question Paper Pdf

Get the official AQA GCSE Combined Science: Trilogy Chemistry Paper 2 Higher Tier question paper from the June 2025 exam series (8464/C/2H). This examiner-authentic PDF contains the complete Higher Tier Chemistry Paper 2 in its original AQA exam layout, including viscosity investigations, atmosphere-composition analysis, crude-oil calculations, cracking and hydrocarbon tests, equilibrium questions, rate-of-reaction practicals, tangent-gradient calculations, bioleaching, and extended-response chemistry questions exactly as candidates received them in the live examination.

This 2025 Chemistry 2H paper assesses alkanes, dodecane viscosity, control variables, atmospheric gases, greenhouse gases, sulfur dioxide emissions, finite resources, crude oil fractions, catalytic and steam cracking, hydrocarbons and polymers, equilibrium in methanol production, catalysts, Le Chatelier’s principle, rates of reaction, sodium thiosulfate investigations, magnesium and hydrochloric acid reactions, gradient calculations from graphs, Avogadro calculations, bioleaching, phytomining, and recycling metals from electronic waste across the AQA GCSE Combined Science specification. Pair it with the matching AQA 8464/C/2H mark scheme on markscheme.net for complete examiner-standard revision, self-marking, and timed mock-exam practice. Updated for the 2025/2026 academic year, optimised for mobile and desktop, and instantly downloadable from markscheme.net.

This document is designed for GCSE Combined Science: Trilogy Higher Tier students preparing for the 2026 AQA examination series, including Year 11 candidates targeting grades 7–9, resit students improving previous GCSE Chemistry results, and home-educated learners following the AQA 8464 specification. It is especially valuable for practising Higher Tier chemistry calculations, graph interpretation, tangent-gradient methods, equilibrium explanations, required practical analysis, and six-mark extended responses under authentic exam conditions.

It is also essential for chemistry teachers, science departments, private tutors, revision-course providers, and parents supporting GCSE revision at home. The paper can be used for classroom mocks, intervention sessions, retrieval-practice tasks, structured revision programmes, and examiner-style assessment using the official June 2025 mark scheme.
