The catalytic converter in the car's exhaust system which converts polluting exhaust gases into non-toxic one contains a _________ catalyst.

Options

A. heterogeneous
B. enzyme
C. homogeneous
D. acid-base

Answer

A

Explanation

In a single pass through the catalyst bed, `CO` and unburned petrol are oxidized to `CO_(2)` and `H_(2)O` , while `NO` is reduced to `N_(2)` Mixtures of transition metals `(Pt, Pd and Ru)` and their oxides embedded in inert supports act as the catalyst.
`2CO+O_(2)overset(Catalyst)(rarr)2CO_(2)`
Hydrocarbons (unburnet petrol)
`overset(Catalyst)(rarr)CO_(2)+H_(2)O`
`2NOoverset(Catalyst)(rarr)N_(2)+O_(2)`
