Answer 1

Answer:

here is ur answer bro

Asbestos is a silicate mineral which shows good adsorption properties. Asbestos whose outer surface is coated with platinum is called platinised asbestos.

By activity, we basically mean the action (mode and functioning) of a substance. For example, by activity of a catalyst we mean that how the catalyst functions and catalyses a reaction. To enhance the activity of a catalyst means to enhance the ability of a catalyst to catalyse a reaction. It is an important feature of solid catalyst and depends upon the extent of chemisorption to a large extent. The process by which an adsorbed or absorbed substance is removed from or through a surface is known as desorption. It is simply the opposite of absorption or adsorption.

Answer 2

Answer:

Asbestos whose outer surface is coated with platinum is called platinised asbestos. By activity, we basically mean the action (mode and functioning) of a substance. ... The process by which an adsorbed or absorbed substance is removed from or through a surface is known as desorption

Platinised asbestos is a solid catalyst whereas the reactants SO2 and O2 and product SO3

are in gas phase in the manufacture of sulfuric acid. So the above process is heterogeneous catalysis.
