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. $\frac{\mathrm{x}}{\mathrm{m}}$ is proportional to

• A

  ${\mathrm{P}}^{\frac{1}{4}}$
• B

  ${\mathrm{P}}^2$
• C

  P
• Correct answer
  D

  ${\mathrm{P}}^{\frac{1}{2}}$

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