The adsorption of a gas on a solid surface follows the Freundlich adsorption isotherm. At $T(K)$,the gas pressure is $2 \ atm$. What is the value of $\frac{x}{m}$? (Given: $n=2$ and $k=$ constant)

• A
  $\frac{x}{m}=4 k$
• B
  $\frac{x}{m}=\frac{1.414}{k}$
• C
  $\frac{x}{m}=\frac{k}{1.414}$
• D
  $\frac{x}{m}=1.414 k$
