The correct order of adsorption of the following gases on the surface of charcoal is: $H_2$ $(I)$,$CH_4$ $(II)$,$SO_2$ $(III)$.

Plot of $\log \left( \frac{x}{m} \right)$ against $\log P$ is a straight line inclined at an angle of $45^o$. When the pressure is $0.5 \ atm$ and Freundlich parameter,$k$ is $10$,the amount of solute adsorbed per gram of adsorbent will be ...... $g$ $(\log 5 = 0.6990)$

Why does the white precipitate of silver halide become coloured in the presence of dye eosin?

Adsorption of a gas on solids follows Freundlich adsorption isotherm. The graph drawn between $\log \frac{x}{m}$ (on y-axis) and $\log p$ (on x-axis) is a straight line with slope equal to $3$ and intercept equal to $0.30$. What is the value of $\frac{x}{m}$ at a pressure of $2 \ atm$?
(Given; $\log 2 = 0.3$ )

In the adsorption of a gas on a solid,the Freundlich isotherm is obeyed. If the slope of the plot of $\log(\frac{x}{m})$ versus $\log(p)$ is zero,then the extent of adsorption is:

When a graph is plotted between $\log (x/m)$ and $\log P$,it is a straight line with an angle of $45^o$ and an intercept of $0.3010$ on the $y-$axis. If the initial pressure is $0.3 \ atm$,what will be the amount of gas adsorbed per $g$ of adsorbent $(x/m)$?
