Edexcel IAL Chemistry A2 17.29 catalytic converters and platinum
Describe the heterogeneous sequence clearly: CO or NO adsorbs on platinum, bonds weaken, reaction occurs on the surface, then CO2 or N2 desorbs.
How this is tested
- Describe CO or NO adsorption onto the platinum catalyst surface in the converter.
- Explain bond weakening, surface reaction and desorption of CO2 or N2 products.
- Compare platinum converter catalysis with V2O5 catalyst cycling when prompted.
