Question 5.4:

Why is it necessary to remove CO when ammonia is obtained by Haber’s process?

Answer:

It is important to remove CO in the synthesis of ammonia as CO adversely affects the activity of the iron catalyst, used in Haber’s process.

Question 5.5:

Why is the ester hydrolysis slow in the beginning and becomes faster after sometime?

Answer:

Ester hydrolysis can be represented as:

The acid produced in the reaction acts as a catalyst and makes the reaction faster. Substances that act as catalysts in the same reaction in which they are obtained as products are known as autocatalysts.

Question 5.6:

What is the role of desorption in the process of catalysis?

Answer:

The role of desorption in the process of catalysis is to make the surface of the solid catalyst free for the fresh adsorption of the reactants on the surface.
