The adsorption of a gas on a solid surface follows the Freundlich adsorption isotherm. At $T(K)$,the gas pressure is $2 \ atm$. What is the value of $\frac{x}{m}$? (Given: $n=2$ and $k=$ constant)
Assertion : The enthalpy of physisorption is greater than chemisorption.
Reason : Molecules of adsorbate and adsorbent are held by van der Waal's forces in physisorption and by chemical bonds in chemisorption.
