Adsorption of a gas follows Freundlich adsorption isotherm. $\mathrm{x}\mathrm{ }$is the mass of the gas adsorbed on mass $\mathrm{m}$ of the adsorbent. The plot of $\log \frac{\mathrm{x}}{\mathrm{m}}$ vs  $\log \left(\mathrm{p}\right)$  is shown in the given graph. $\frac{\mathrm{x}}{\mathrm{m}}$ is proportional to,

• A

  ${\mathrm{p}}^3$
• B

  ${\mathrm{p}}^2$
• Correct answer
  C

  ${\mathrm{p}}^{2/3}$
• D

  ${\mathrm{p}}^{3/2}$

Hence, the correct answer is option: 'C'.
