If $x$ amount of gas is adsorbed on $m$ amount of adsorbent at pressure $p$,the Freundlich adsorption isotherm plot gives a straight line for which of the following?

• A
  $\frac{x}{m}$ vs $p$
• B
  $\log(\frac{x}{m})$ vs $\log(p)$
• C
  $\log(\frac{x}{m})$ vs $p$
• D
  $\frac{x}{m}$ vs $\frac{1}{p}$
