Adsorption of a gas follows Freundlich adsorption isotherm. xx is the mass of the gas adsorbed on mass mm of the adsorbent. The plot of xm\frac{x}{m} versus log⁡p\log p is shown in the given graph. Adsorption of a gas follows Freundlich adsorption isotherm. x is the mass of the gas adsorbed on mass m of the
xm\frac{x}{m} is proportional to :

Options

  1. Ap2/3p^{2 / 3}
  2. Bp3/2p^{3 / 2}
  3. Cp3p^{3}
  4. Dp2p^{2}

Correct answer

A. p2/3p^{2 / 3}

Step-by-step solution

According to Freundlich adsorption isotherm xm∝p1n,xm=kp1n\frac{x}{m} \propto p^{\frac{1}{n}}, \frac{x}{m}=k p^{\frac{1}{n}} Slope =23log⁡xm=log⁡k+1nlog⁡p=\frac{2}{3}\log \frac{x}{m}=\log k+\frac{1}{n} \log p Slope =1n=23xm∝p23=\frac{1}{n}=\frac{2}{3}\frac{x}{m} \propto p^{\frac{2}{3}}
