The validity of the Freundlich isotherm can be verified by plotting:

During the adsorption of a gas on the surface of a solid,which of the following is true?

What should be taken on the $Y$-axis in the Freundlich adsorption isotherm plot to obtain a straight line?

To form a complete monolayer of acetic acid on $1 \ g$ of charcoal,$100 \ mL$ of $0.5 \ M$ acetic acid was used. Some of the acetic acid remained unadsorbed. To neutralize the unadsorbed acetic acid,$40 \ mL$ of $1 \ M$ $NaOH$ solution was required. If each molecule of acetic acid occupies $P \times 10^{-23} \ m^2$ surface area on charcoal,the value of $P$ is $\qquad$
[Use given data : Surface area of charcoal $= 1.5 \times 10^2 \ m^2 \ g^{-1}$; Avogadro's number $(N_A) = 6.0 \times 10^{23} \ mol^{-1}$]

Which substance is used as an adsorbent in chromatography?

For a gas-solid adsorbent system,the adsorption isotherm $\frac{x}{m}=k p^{1/n}$ is applicable,where $n=5$ in the specified case. Point out the correct statement:
