0A graph between \( x / m \) and the pressure \( P \) of the gas at a constant temperature is called adsorption isotherm. Where \( x \) is the no. of moles of the adsorbate and \( m \) is the mass of the adsorbent. Adsorption isotherms of different shapes have been experimentally observed. According to Frundlich adsorption isotherm.
where \( k \) and \( n \) are constant parameters depending upon the nature of the solid and gas.
In the given isotherm select the incorrect statement:
(a) \( \frac{x}{m} \propto P^{1 / n} \) along \( O A \)
(b) \( \frac{x}{m} \propto P^{0} \) when point \( B \) is reached
(c) \( \frac{x}{m} \) does not increase as rapidly with pressure along \( B C \) due to less surface area available for adsorption
(d) nature of isotherm is different for two gases for same adsorbent
