This diagram covers Four Factors Affecting Rate of Reaction within Factors Affecting Rate for GCSE Chemistry. Revise Factors Affecting Rate in Rates of Reaction for GCSE Chemistry with 24 exam-style questions and 18 flashcards. This topic shows up very often in GCSE exams, so students should be able to explain it clearly, not just recognise the term. It is section 3 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.
📐 Four Factors Affecting Rate of Reaction
Figure 1: How each factor affects particle collisions. Temperature and concentration increase collision frequency; catalyst lowers the activation energy barrier.
