Question

Heterogeneous catalyst used in Ostwald's process for
manufacture of nitric acid is

CuCl2
Finely divided Nickel
ZnO + Cr203
Platinised asbestos​

Answer 1

Answer:

Substances, which accelerate the rate of a chemical reaction and themselves remain chemically and quantitatively unchanged after the reaction, are known as catalysts.

In Haber's process for manufacturing of NH

3

, Fe, and Mo are used as catalyst and promoter respectively.

In contact process of manufacturing Sulfuric acid V

2

O

5

, may also be used as a catalyst.

Platinised asbestos is used as a catalyst for Ostwald's process for the manufacture of nitric acid.

Hence, Fe

2

O

3

is not used in Ostwald's process and hence it is the correct
