Question

The gas which is more adsorbed on activated charcoal is:
A.$S{O_2}$
B.${N_2}$
C.${O_2}$
D.${H_2}$

Answer 1

First we need to realize that adsorption. This adsorption is the surface wonders wherein aggregation of the substance happens in the higher focus. The substance that adsorbed is called adsorbate and the surface on which it gets adsorbed is called adsorbent.

Complete answer:
We have to know that activated controlled charcoal is a type of carbon. It is created to have little, low-volume pores that expand the surface space of charcoal accessible for adsorption. Charcoal utilized in gas covers is disclosed to the environmental air so its surface can adsorb gas and water fumes. For the most part, effectively liquefiable gases are $C{O_2}$ , $C{l_2}$ , $S{O_2}$ .
These gases are ingested more than lasting gases, for example, ${H_2}$ , ${O_2}$ , ${N_2}$ . Assimilation relies upon the basic temperature. Gases which have a more basic temperature are consumed more. Subsequently, the basic temperature of
Hydrogen (${H_2}$ ) is $33K$
Sulfur dioxide ($S{O_2}$ ) is $630K$
Nitrogen (${N_2}$ ) is $126.2K$
Oxygen (${O_2}$ ) is $154.6K$
Where,the lowest critical point temperature is hydrogen (${H_2}$ ) and this hydrogen gas is difficult to absorb.
Then, the highest critical point temperature is sulfur dioxide. Because it is easily absorbed. So that in the given four gases, more absorbed in activated charcoal is sulfur dioxide ($S{O_2}$ ).

Therefore,the correct option is (A).

Note:
The basic temperature is additionally, identified with molar mass and by the determination of molar mass, we can track down that the gas that has higher molar mass, its basic temperature is high. So that sulfur dioxide comes into the air fundamentally from copper refining, oil at power plants, and the consumption of charcoal. It has a severe taste. It might aggravate the eyes.
