The exam evaluates advanced chemistry concepts, focusing on reaction rates, organic chemistry, polymers, environmental sustainability, and industrial processes. Key topics include fractional distillation, reversible reactions, chromatography, polymer properties, and equilibrium principles. Practical applications involve calculating Rf values, analyzing reaction profiles, and balancing chemical equations. Emphasis is placed on the Haber process, sustainability in industrial production, water treatment methods, and atmospheric chemistry changes. Tasks require interpreting experimental data, evaluating industrial applications, and understanding molecular structures and reaction conditions. Keywords: GCSE Chemistry, reaction rates, organic chemistry, equilibrium, sustainability, chromatography, polymers, Haber process, industrial processes, environmental impact.
