Adsorption of a gas follows Freundlich adsorption isotherm. x is the mass of the gas adsorbed on mass m of the adsorbent. The plot of x m versus p is shown in the given graph. x m is proportional to :

Options

  1. Ap^ 2 / 3
  2. Bp^ 3 / 2
  3. Cp³
  4. Dp²

Correct answer

A. p^ 2 / 3

Step-by-step solution

According to Freundlich adsorption isotherm x m p^ 1 n , x m =k p^ 1 n Slope = 2 3 x m = k+ 1 n p Slope = 1 n = 2 3 x m p^ 2 3
