Edexcel IAL Chemistry A2 11.7 Rate-determining steps
Match rate-law species and powers to reactants involved up to the slow step, then add all steps to confirm the correct overall stoichiometric equation.
How this is tested
- Reject a proposed slow step when it contains a reactant absent from the measured rate equation.
- Derive a rate equation from the molecularity and species in a stated slow elementary step.
- Check a mechanism by matching both its rate-determining step and summed overall equation.
