Revise Displacement Reactions in Chemical Changes for GCSE Chemistry with 22 exam-style questions and 20 flashcards. Use this page as part of a wider topic revision path rather than treating it as an isolated fact. It is section 6 of 13 in this topic. Focus on the labels, the relationships between parts, and the explanation that turns the diagram into an exam-ready answer.
🔥 Displacement Reactions Release Energy
Figure 2: Energy level diagrams for exothermic and endothermic reactions
Displacement reactions are exothermic — they release energy because stronger bonds form in the products than those broken in the reactants. This is why the reaction mixture warms up when a more reactive metal is added to a salt solution.
