If `x` is the amount of adsorbate and `m` is the amount of adsorbent, which of the following relation is related to adsorption process?

Options

A. `(x)/(m)=pxxT`
B. `(x)/(m)=f(p)` at constant `T`
C. `(x)/(m)=f(T)` at constant `P`
D. `p=f(T)` at constant `(x//m)`

Answer

A

Explanation

According to adsorption isobar `(x//m)` is a function of temperature `(T)` at constant `P` . According to adsorption isotherm, `(x//m)` is a functions of pressure `(P)` at constant temperature `(T)` . According to adsoption isostere, a linear relationship exists between temperature and pressure at constant `(x//m)` .
Thus, `x//m=PxxT` , is not related to adsorption process. The correct relation is `(x)/(m)prop(P)/(T)`
