Previous Years AIEEE/JEE Main Questions
(1) Under high pressure it results into multi molecular layer on adsorbent surface (2) Enthalpy of adsorption $\left(\Delta \mathrm{H}_{\text {adsorption }}\right)$ is low and positive (3) It occurs because of Van der Waal’s forces (4) More easily liquefiable gases are adsorbed readi AIEEE-2009
$\Delta \mathrm{H}$ is negative
(1) $\frac{\mathrm{x}}{\mathrm{m}} \propto \mathrm{p}^{0}$ (2) $\frac{\mathrm{x}}{\mathrm{m}} \propto \mathrm{p}^{1}$ (3) $\frac{\mathrm{x}}{\mathrm{m}} \propto \mathrm{p}^{1 / \mathrm{n}}$ (4) All the above are correct for different ranges of pressure AIEEE-2012
