Exam Focus: Reversible Reactions
This exam focus covers Exam Focus: Reversible Reactions within Reversible Reactions for GCSE Chemistry. Revise Reversible Reactions in Rates of Reaction for GCSE Chemistry with 20 exam-style questions and 12 flashcards. This topic appears regularly enough that it should still be part of a steady revision cycle. It is section 10 of 12 in this topic. Treat this as a marking guide for what examiners are looking for, not just a fact list.

🎯 Exam Focus: Reversible Reactions
high Energy questions (2-3 marks): State the direction (forward/backward), whether it is exo or endothermic, and the energy rule.
high Copper sulfate test (2 marks): Know the colour change (white → blue with water) and explain using the reversible reaction equation.
medium Symbol questions (1 mark): Use ⇌ not → in equations for reversible reactions. This is a commonly penalised error.
Common exam question: "Explain what happens when water is added to anhydrous copper sulfate" — must include: colour change, exothermic, equation with ⇌ symbol.
Edexcel 1CH0: Examined in Paper 2 (1CH0/2). Edexcel tests the concept of dynamic equilibrium and the effect of changing conditions on reversible reactions. In Edexcel-style questions, the command word "Suggest" appears frequently — use your chemistry knowledge to apply to an unfamiliar context.
