Which of the following option is correct for given curve?

Options

  1. Ax m ∝ P
  2. Bx m ∝ P 2
  3. Cx m ∝ P 1 / 2
  4. Dx m ∝ P 0

Correct answer

C. x m ∝ P 1 / 2

Step-by-step solution

According to the Freundlich adsorption isotherm, x m = K p 1 n Taking log on bot sides. l o g x m = l o g K + 1 n log ⁡ P Slope = 1 n Slope from graph = y 2 - y 1 x 2 - x 1 = 2 4 = 1 2 or, 1 n = 1 2 ∴ x m = K p 1 2 or x m ∝ p 1 2
