If $x$ is the mass of the gas adsorbed on mass $m$ of the adsorbent at pressure $p,$ Freundlich adsorption isotherm gives a straight line on plotting

The correct order of adsorption of the following gases on the surface of charcoal is: $H_2$ $(I)$,$CH_4$ $(II)$,$SO_2$ $(III)$.

For the adsorption of a solution on a solid surface,the Freundlich adsorption isotherm is given by $\frac{x}{m} = k C^{1/n}$. The plot of $\log (\frac{x}{m})$ versus $\log C$ is shown below. This corresponds to which of the following conditions?

Which one of the following statements is correct?

Select the correct statement.

Compare the enthalpy of chemical adsorption with physical adsorption.
