Dynamic equilibrium and "how far" a reaction goes
Dynamic equilibrium and "how far" a reaction goes
Many reactions are reversible, so products can react to reform reactants. In a closed system, they can reach dynamic equilibrium, where the forward and reverse reactions continue at equal rates.
Step-by-step lessons on OCR A A Level Chemistry How far?. Each one builds up to exam-style questions. 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.
