Question

How to carry out cracking with heterogeneous catalyst in lab?

Answer 1

Heterogeneous catalysis involves adsorption, activation, reaction, and desorption processes. Examples include the interaction of hydrogen gas with a metal surface and the production of ammonia, nitric acid, sulfuric acid, and methanol.

Step-by-step explanation:

Heterogeneous catalysis involves several processes:

1. Adsorption of the reactant(s) onto the surface of the catalyst.
2. Activation of the adsorbed reactant(s).
3. Reaction of the adsorbed reactant(s).
4. Desorption of product(s) from the surface of the catalyst.

An example of heterogeneous catalysis is the interaction of hydrogen gas with the surface of a metal, such as Ni, Pd, or Pt. The adsorbed hydrogen atoms on the metal surface are more reactive than a hydrogen molecule, allowing for lower energy barriers for reactions to occur. Several important examples of industrial heterogeneous catalytic reactions include the production of ammonia, nitric acid, sulfuric acid, and methanol.
