Which one of the following equations represents the Freundlich adsorption isotherm?

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 number of incorrect statement/s from the following is/are:
$A.$ Water vapours are adsorbed by anhydrous calcium chloride.
$B.$ There is a decrease in surface energy during adsorption.
$C.$ As the adsorption proceeds,$\Delta H$ becomes more and more negative.
$D.$ Adsorption is accompanied by decrease in entropy of the system.

If a dilute solution of $AgNO_3$ is added to a dilute solution of excess $NaI$,then the species adsorbed on $AgI$ colloidal particles is:

If the initial pressure of a gas is $0.03 \, atm$,the mass of the gas adsorbed per gram of the adsorbent is $...... \, \times 10^{-2} \, g$. Based on the provided graph,determine the value.

Which among the following statements is false?
