Edexcel IAL Chemistry AS 9.9 Reversible reactions and dynamic equilibrium
State both defining conditions without claiming reactions stop or concentrations are equal, then use rate, concentration or mole data to test equilibrium conclusions.
How this is tested
- Define dynamic equilibrium as equal opposing rates with constant concentrations.
- Interpret rate or concentration graphs to identify when equilibrium has been reached.
- Use balanced-equation changes to calculate amounts in an equilibrium mixture.
