$A$ plot of $\log \left( \frac{x}{m} \right)$ vs $\log \, P$ for the adsorption of a gas on a solid gives a straight line with slope equal to

Which of the following statements is not correct?

$A$ charcoal cube having side length $10 \ cm$ is chopped lengthwise into $5$ equal pieces. Then the effective adsorption power

Which of the following statements is true for adsorption?

The plot of $\log \frac{x}{m}$ ($y$-axis) and $\log p$ ($x$-axis) is a straight line inclined at an angle of $45^{\circ}$. When the intercept is $\log K = 0.3010$ (where $K = 2$) and pressure is $0.3 \ atm$,calculate the amount of solute in grams adsorbed per gram of adsorbent $\frac{x}{m}$ (given $\log 3 = 0.4771$ and $\log 0.3 = -0.5229$)?

Adsorption of a gas follows Freundlich adsorption isotherm. If $x$ is the mass of the gas adsorbed on mass $m$ of the adsorbent,the correct plot of $\frac{x}{m}$ versus $p$ is:
