Edexcel IAL Chemistry A2 13.4 Factors affecting equilibrium composition
Use gaseous mole numbers for pressure and reaction enthalpy for temperature, while stating that a catalyst speeds both directions equally and does not shift equilibrium.
How this is tested
- Predict pressure effects from gas mole numbers and connect the shift to yield or colour.
- Use reaction enthalpy to predict the effect of temperature on equilibrium composition.
- Explain that catalysts change equilibration rate but not equilibrium position or composition.
