Why does physisorption decrease with the increase of temperature?
(N/A) Physisorption is an exothermic process. According to Le Chatelier's principle,for an exothermic process,an increase in temperature shifts the equilibrium in the backward direction. Therefore,physisorption decreases as the temperature increases,and it occurs more readily at lower temperatures.

View SolutionIf the value of $\frac{1}{n}$ is equal to $1$ in the Freundlich adsorption isotherm,then $\frac{x}{m} = $ (where $x = $ mass of adsorbate,$m = $ mass of the adsorbent,$p = $ pressure of the gas).
If $x$ is the amount of adsorbate and $m$ is the amount of adsorbent,which of the following relations is not related to the adsorption process?
