I’ve got this list of topics and I’m trying to figure out which past paper it came from (Edexcel IAL chemistry Unit 2 WCH12). It’s a Jan or May paper 2021-2025.
• Redox reactions and oxidation numbers: Identifying oxidation and reduction using oxidation states.
• Group 7 chemistry: Trends in reactivity, displacement reactions and halogen properties.
• Energetics calculations: Using bond enthalpies and calorimetry data to calculate energy changes.
• Rates of reaction experiments : Investigating how concentration and temperature affect rate.
• Halogenoalkane mechanisms: SN1, SN2 and elimination mechanisms under different conditions.
• Alcohol reactions: Chemical behaviour of alcohols including oxidation and substitution.
• Acid-base titration curves: Interpreting titration data and end points.
