Select ALL correct statements about a Pt-Rh-Pd three-way catalytic converter.

ACO is oxidised to $CO X_{2}$
BUnburnt hydrocarbons are oxidised to $CO X_{2}$ and $H X_{2} O$
CIt is a homogeneous catalyst dissolved in the exhaust gases
DNO is reduced to $N X_{2}$

Answer: A, B, D

The converter converts CO, NO and hydrocarbons into

CO X_{2}

,

N X_{2}

and

H X_{2} O

on a solid metal surface. A solid catalyst acting on gaseous reactants is heterogeneous, so the last statement is false.
