Dynamic equilibrium and what KKK measures
Dynamic equilibrium and what KKK measures

A reversible reaction reaches dynamic equilibrium only in a closed system. At equilibrium, the forward and reverse reactions continue at equal rates, so concentrations stay constant but are not usually equal.
Step-by-step lessons covering Edexcel A Level Chemistry Kc and Kp equilibria 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.
