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 log x m vs log p is shown in the given graph. x m is proportional to,

Options

  1. Ap 3
  2. Bp 2
  3. Cp 2 / 3
  4. Dp 3 / 2

Correct answer

C. p 2 / 3

Step-by-step solution

According to Freundlich adsorption Isotherm, x m = k P 1 n log ⁡ x m = log ⁡ k + 1 n log ⁡ p y = m x + c ;     m = 1 n ; from the graph, m = 2 3 x m = k P 2 3 x m ∝ P 2 3 .
