Acetic acid adsorbed on activated charcoal is . . . . .

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

Identify the example of sorption from the following.

Adsorption of a gas on a solid adsorbent follows the Freundlich adsorption isotherm. If $x$ is the mass of the gas adsorbed on mass '$m$' of the adsorbent at pressure $p$, then from the given graph, the extent of adsorption is proportional to:

Adsorption is multilayer in the case of

Assertion : In chemisorption,adsorption first increases with temperature and then decreases.
Reason : Heat keeps on providing more and more activation energy.
