Which of the following is true for the adsorption of $Krypton$ on the surface of activated charcoal at low temperature?

In the figure,a straight line is given for the Freundlich Adsorption isotherm equation $(y = mx + c)$,where the equation is $y = 0.3x + 0.7033$. The values of $\frac{1}{n}$ and $\log K$ are respectively:

The following statements relate to the adsorption of gases on a solid surface. Identify the incorrect statement among them.

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).

What is an adsorption isotherm? Describe Freundlich adsorption isotherm.

The plot of $\log \frac{x}{m}$ ($y$-axis) and $\log p$ ($x$-axis) is a straight line inclined at an angle of $45^{\circ}$. When the intercept is $\log K = 0.3010$ (where $K = 2$) and pressure is $0.3 \ atm$,calculate the amount of solute in grams adsorbed per gram of adsorbent $\frac{x}{m}$ (given $\log 3 = 0.4771$ and $\log 0.3 = -0.5229$)?
