Noble gases are adsorbed on

Plot of $\log \left( \frac{x}{m} \right)$ against $\log P$ is a straight line inclined at an angle of $45^{\circ}$. When the pressure is $0.5 \ atm$ and Freundlich parameter $(K)$ is $10$,then the amount of solute adsorbed per gram of adsorbent is .......... $g$ $(\log 5 = 0.699)$.

Which of the following compounds is formed when tungsten adsorbs oxygen gas?

In the neutralisation of $KI$ by $AgNO_3$,the positive charge on the colloidal particles is due to the adsorption of:

What is the effect of pressure on the extent of adsorption?

Which plot is the adsorption isobar for chemisorption?
