According to the Freundlich adsorption isotherm,which of the following is correct?

Which one of the following is correct for the adsorption of a gas at a given temperature on a solid surface?

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

Assertion : The relation $\frac{x}{m} = k \cdot p^{1/n}$ is known as Freundlich adsorption isotherm,where $x$ is the mass of gas adsorbed by $m$ grams of adsorbent,$p$ is the equilibrium pressure,$k$ and $n$ are constants for a given system and temperature.
Reason : When several substances have the same value of $\frac{1}{n}$,the lines by which their adsorption isotherms can be represented will meet at a point.

The surface area of $1 \, g$ of activated charcoal is $1000 \, m^2$. Assuming complete coverage and unimolecular adsorption,if the radius of an ammonia molecule is $10^{-8} \, cm$,then the volume of ammonia adsorbed at $STP$ on $44/7 \, g$ of carbon will be ........ $L$. $(N_A = 6 \times 10^{23})$
