AQA Chemistry: Paper Two Content
A GCSE AQA Chemistry Paper Two revision hub summarising key topic areas including the rate and extent of chemical change, organic chemistry, chemical analysis, Chemistry of the atmosphere, and using resources with links to detailed topic pages and clear explanations.
Paper Two
THE RATE AND EXTENT OF CHEMICAL CHANGE
A GCSE chemistry revision page on groups in the periodic table covering the alkali metals’ properties and reactivity trends, noble gas inertness and uses, halogen states and reactivity patterns, reactions with metals, and displacement trends down group 7.
ORGANIC CHEMISTRY
A GCSE revision page on rates of reaction and energy changes including practical methods for measuring rate, collision theory, factors affecting rate, interpreting rate graphs, catalysts, activation energy, reaction profiles, and calculations of rate and energy change.
CHEMICAL ANALYSIS
A GCSE chemistry revision page on hydrocarbons covering alkanes and alkenes, combustion reactions, cracking to produce smaller alkanes and alkenes, and how these reactions relate to fuel properties and chemical behaviour with examples and explanations.
CHEMISTRY OF THE ATMOSPHERE
A GCSE chemistry revision page on the Earth’s atmosphere, explaining composition and changes over time, greenhouse gases and global warming, formation of pollutants from combustion, carbon footprint ideas, and methods to reduce gas emissions.
USING RESOURCES
GCSE revision page on ions and materials covering flame tests, hydroxide precipitates, tests for ammonium, carbonates, sulfates and halides, an ions core practical, instrumental analysis (flame photometry), plus nanoparticles, ceramics, composites and choosing materials based on properties.
