What rate of reaction means
Reaction rate tells you how fast a reaction is happening. It is the change in amount, concentration, mass or volume per unit time.
Step-by-step lessons covering Edexcel A Level Chemistry Rates and rate experiments for A Level Chemistry. Each lesson works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
