The statement not applicable to chemisorption is

When a dilute aqueous solution of $AgNO_3$ (excess) is added to $KI$ solution,positively charged sol particles of $AgI$ are formed due to the adsorption of which ion?

Wood charcoal is used to decolourise sugar because it

The adsorption of hydrogen by metals is called

Adsorption of a gas follows the Freundlich adsorption isotherm. $x$ is the mass of the gas adsorbed on mass $m$ of the adsorbent. The plot of $\log \frac{x}{m}$ versus $\log p$ is shown in the given graph. $\frac{x}{m}$ is proportional to:

The correct option$(s)$ related to adsorption processes is(are):
$A$. Chemisorption results in a unimolecular layer.
$B$. The enthalpy change during physisorption is in the range of $100$ to $140 \ kJ \ mol^{-1}$.
$C$. Chemisorption is an endothermic process.
$D$. Lowering the temperature favors physisorption processes.
