Which among the following statement is false
A. The adsorption may be monolayered or multilayered
B. Particle size of adsorption will not affect the amount of adsorption
C. Increase of pressure increases amount of adsorption
D. Increase of temperature may decrease the amount of adsorption

Hint: Physical adsorption lacks chemical specificity; if the temperature is low enough or the gas pressure is high enough, any gas will tend to adsorb on any material. Chemical forces that are unique to each surface and each gas hold gases to a solid surface during chemical adsorption.

Complete Step by Step Solution:
For this solution we will justify the answer for any point according to the options, we take all the points separately by which we can easily say that, which statement is false,

For option A, Adsorption can indeed be either monolayered or multilayered. The adsorption of gases increases when the surface area of the adsorbent is increased.

For option B, as we know that, the reason for this is that more adsorbing sites are present when the surface area is increased. The amount of adsorption will therefore depend on the adsorbent's particle size, making Option B untrue.

Similarly for option C, the rate of adsorption initially rises as the pressure is elevated because more gas molecules are impacting the surface. As a result, the rate of adsorption increases linearly as pressure increases.

Now for option D, the rate of adsorption initially increases when pressure rises as a result of more gas molecules contacting the surface. As a result, a linear relationship exists between pressure and adsorption rate.

As from the whole conclusion, we get that, Particle size of adsorption will not affect the amount of adsorption is the false statement.
Therefore, the correct answer is Particle size of adsorption will not affect the amount of adsorption.
Hence, the correct option is (B).

Note: It should be noted that, as the temperature rose, the mobility of ions or molecules in the moving water increased, giving rise to an increase in their kinetic energy. In order to increase the adsorption capacity of the adsorbent for lead ions, the pace at which lead ions moved to the surface of the material quickened.
