The extent of adsorption of a gas on a solid depends on:

Why does physical adsorption decrease with an increase in temperature?

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 $\log 0.3 = -0.5229$)?

$A$ mixture of gases $O_2$,$H_2$,and $CO$ are taken in a closed vessel containing charcoal. The graph that represents the correct behaviour of pressure with time is

$A$ particular adsorption process has the following characteristics: $(i)$ It arises due to van der Waals forces and $(ii)$ it is reversible. Identify the correct statement that describes the above adsorption process.

Given below are two statements.
Statement-$I$: Easily liquefiable gases are readily adsorbed.
Statement-$II$: Adsorption enthalpy for physisorption is less compared to adsorption enthalpy for chemisorption.
The correct answer is
