Animal charcoal is used in decolourising liquids because it is a good

If the value of $\frac{1}{n}$ is equal to $1$ in the Freundlich adsorption isotherm, then $\frac{x}{m} = $ (where $x = $ mass of adsorbate, $m = $ mass of the adsorbent, $p = $ pressure of the gas).

The validity of the Freundlich isotherm can be verified by plotting:

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R.$
Assertion $A:$ $SO_{2(g)}$ is adsorbed to a larger extent than $H_{2(g)}$ on activated charcoal.
Reason $R:$ $SO_{2(g)}$ has a higher critical temperature than $H_{2(g)}.$
In the light of the above statements,choose the most appropriate answer from the options given below.

Which type of adsorption leads to the formation of a multimolecular layer?

What type of the graph $\log(x/m)$ vs $\log P$ is obtained for the Freundlich adsorption isotherm?
