Question

If x is the amount of adsorbate and m is the amount of adsorbent, which of the following relations is not related to adsorption process?

• A. $\frac{x}{m}=p\times T$
• B. $\frac{x}{m}=f\left(p\right)$ at constant T
• C. $\frac{x}{m}=f\left(T\right)$ at constant p
• D. $p=f\left(T\right)$at constant $\left(\frac{x}{m}\right)$

Answer 1

Answer: (A)

$\frac{x}{m}=p\times T$

Since only adsorption isotherms & adsorption isobars are plotted.

That is either temperature or pressure is kept constant.

It can't be plotted when none of pressure or temperature is constant.
