Question

Adsorption of a gas follows Freundlich adsorption isotherm. In the given plot, x is the mass of the gas adsorbed on mass m of the adsorbent at pressure P . x m is proportional to:, p 1 4, p, p 2, p 1 2

According to the Freundlich adsorption isotherm, x m = K p 1 n Taking log on both sides. l o g x m = l o g K + 1 n log ⁡ P Slope from graph = y 2 - y 1 x 2 - x 1 = 2 4 = 1 2 or, 1 n = 1 2 ∴ x m = K p 1 2 or x m ∝ p 1 2
