Which gas will be adsorbed on a solid to a greater extent?

Adsorption due to strong chemical forces is called

According to the Freundlich adsorption isotherm,a straight line is obtained for the plot of:

Which type of bond is involved in the phenomenon of physical adsorption?

Which one of the following characteristics is not correct for physical adsorption?

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.
