A Levels Chemistry

Which reaction in the catalytic converter does not remove hazardous and polluting gases from
the exhaust fumes of a motor car?
gases going out
gases going in:
carbon monoxide,
hydrocarbons
and oxides of
nitrogen
surfaces coated
with platinum and
rhodium catalyst
These equations are qualitative and unbalanced.
[HC = unburnt hydrocarbons; NO, = oxides of nitrogen]
%3D
А HC + NOx НаО + СО + N
B
Со + NOx > CО2 + N2
НС + NOx > Н-0 + CO2 + N2
D CO + O2 → CO2
