The GCSE Chemistry J248/02 (June 2018) paper explores advanced concepts in chemistry, including Group 1 and Group 7 elements, hydrocarbons, polymers, and reversible reactions. Section A tests foundational knowledge of reactivity, bonding, and chemical processes. Section B applies these principles to real-world contexts, such as titrations, electrolysis, life-cycle assessments, and fuel cells. Key topics include rate of reaction, equilibrium, and environmental impacts like greenhouse gases. The paper emphasizes data interpretation, practical applications, and critical evaluation of scientific methods and results.
