Question
Give four examples of heterogeneous catalysis.
Solution
Answer:
Heterognous catalysis :
The catalytic process in which the reactant and the catalyst are in different phase is known as heterogenous catalyst.
The examples of heterogeneous system are given below:
1. Manufacture of NH3 from N2 and H2 by Haber’s process, using iron as catalyst.
2. Oxidation of NH3 with O2 using Pt as catalyst in Ostwald process.
3. Oxidation of CO in automobile exhaust by platinum catalyst.
4. Hydrogenation of oils to form vegetable ghee using finely divided nickel as catalyst
