This memory aid covers Memory Aid: CCTSP 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 10 of 13 in this topic. Use it for quick recall, then test yourself straight afterwards so the memory aid becomes usable in an answer.
🧠 Memory Aid: CCTSP
Remember the five factors that affect rate of reaction using CCTSP:
- C — Concentration (more particles per volume)
- C — Catalyst (lowers activation energy)
- T — Temperature (faster particles, more exceed Ea)
- S — Surface area (more exposed particles)
- P — Pressure (for gases — same as concentration)
Picture a chef (C) cooking (C) in the Test kitchen (T) with Special (S) Pans (P) — CCTSP rules the kitchen of chemistry!
Practice questions for Factors Affecting Rate
Which of the following factors does NOT affect the rate of a chemical reaction?
Explain, in terms of particles, why increasing temperature increases the rate of reaction.
