A graph is plotted between log (x/m) and log P according to the equation x m = k P 1 n . Which of the following statements about this graph is not correct?

Options

  1. AThe figure shows Freundlich adsorption isotherm
  2. BThe figure shows Langmuir adsorption isotherm
  3. CThe adsorption varies with pressure
  4. DThe factor 1/n can have values between 0 and 1

Correct answer

B. The figure shows Langmuir adsorption isotherm

Step-by-step solution

This is Freundlich isotherm not Langmuir. It is also written as log ⁡ x m = log ⁡ k + 1 n log ⁡ p where x = mass of adsorbate m = mass of adsorbent p = Equilibrium pressure of adsorbate K and n are constants for a given adsorbate and adsorbent at a particular temperature.
