Adsorption Isotherms — Prelims Questions

Which of the following statements is INCORRECT regarding the Freundlich adsorption isotherm?

For a Langmuir adsorption isotherm, a plot of $1/(x/m)$ versus $1/P$ gives a straight line with a slope of $2.0,\text{atm} cdot \text{g/mg}$ and a y-intercept of $0.1,\text{g/mg}$. Calculate the maximum adsorption capacity, $(x/m)_{max}$.

Which of the following is NOT an assumption of the Langmuir adsorption isotherm?

For the adsorption of a gas on a solid, if the plot of $log(x/m)$ versus $log P$ is linear with a positive slope, which isotherm model is likely being followed?

If the value of $1/n$ in the Freundlich adsorption isotherm is 0, what does it imply about the extent of adsorption?

An adsorbent has a maximum adsorption capacity of $50,\text{mg/g}$ and a Langmuir constant $b = 0.2,\text{atm}^{-1}$. What is the extent of adsorption ($x/m$) at an equilibrium pressure of $10,\text{atm}$?
