Question

Why are the catalysts used in industrial manufacture of ammonia, sulfur trioxide etc. kept in a finely divided state?​

Answer 1

Answer:

Catalysts speed up a chemical reaction by lowering the amount of energy you need to get one going. Catalysis is the backbone of many industrial processes, which use chemical reactions to turn raw materials into useful products. Catalysts are integral in making plastics and many other manufactured items.

Answer 2

The catalysts used in the industrial manufacture of ammonia, sulfur trioxide etc. are kept in a finely divided state because it provides a large surface area.

• A catalyst is a chemical substance or element that aids in the speeding up of a reaction without actually interfering in the chemical reaction.
• The catalytic efficiency increases as the surface area increases. A catalyst in a finely split state is more efficient than a non-spilt one.
• For example, finely divided iron is used as a catalyst in Haber's process. The catalyst will help to increase the rate of the reaction or speed up the reaction, it will not affect the production of ammonia.
