In a catalytic converter, which mechanism facilitates the conversion of nitrogen oxides (NOx) into nitrogen gas (N2)?

💡 Explanation

In a catalytic converter, redox reactions promoted by platinum and rhodium catalysts occur because they provide surface sites which lower activation energy for bond breaking and formation to convert NOx to N2 and O2. Therefore, redox reactions result, rather than adsorption, homolytic cleavage or hydrogen which are less prevalent mechanisms here.
