Comprehension \( \quad: \) A graph between \( \mathrm{x} / \mathrm{m} \) and the pressure of the gas at a constant temperature is called adsorption isotherm, where \( x \) is the no. of moles of the adsorbate and \( \mathrm{m} \) is the mass of the adsorbent. Adsorption isotherms of different shapes have been experimentally observed, according to Freundlich adsorption isotherm.
In the given isotherm, select the incorrect statement:
(a) \( \frac{\mathrm{x}}{\mathrm{m}} \propto \mathrm{p}^{1 / \mathrm{n}} \) along OA.
(b) \( \frac{\mathrm{x}}{\mathrm{m}} \propto \mathrm{p}^{0} \) when point \( \mathrm{B} \) is reached.
(c) \( \frac{\mathrm{X}}{\mathrm{m}} \) does not increase as rapidly with pressure along BC due to less surface area available for adsorption.
(d) Nature of isotherm is different for two gases for same adsorbent.
