For a homogeneous catalyst, show it is in the same phase as the reactants and appears in one step before being regenerated in a later step.
How this is tested
- Justify homogeneous catalysis by same phase or same aqueous state as reactants.
- Use mechanisms to show catalyst regeneration rather than consumption overall.
- Explain lower activation energy through alternative steps with more favourable ion reactions.
