A graph is plotted between \log (x/m) and log P according to the equation .

Which of the following statements about this graph is not correct?
Which of the following statements about this graph is not correct?
Options
- AThe figure shows Freundlich adsorption isotherm
- BThe figure shows Langmuir adsorption isotherm
- CThe adsorption varies with pressure
- 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
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.
