This diagram covers Successful vs Unsuccessful Collisions within Rates & Collision Theory for GCSE Chemistry. Revise Rates & Collision Theory in Rates of Reaction for GCSE Chemistry with 25 exam-style questions and 16 flashcards. This topic appears less often, but it can still be a useful differentiator on mixed-topic papers. It is section 2 of 14 in this topic. Focus on the labels, the relationships between parts, and the explanation that turns the diagram into an exam-ready answer.
💥 Successful vs Unsuccessful Collisions
Figure 1: Successful collisions (right) require sufficient energy to overcome the activation energy threshold
