A plot of

\log (x / m)

versus

\log p

for the adsorption of a gas on a solid gives a straight line with slope equal to: A plot of (x / m) versus p for the adsorption of a gas on a solid gives a straight line with slope equal to:

A plot of (x / m) versus p for the adsorption of a gas on a solid gives a straight line with slope equal to:

Options

A $\log \mathrm{K}$
B $-\log \mathrm{K}$
C $n$
D $1 / n$

Correct answer

D. $1 / n$

Step-by-step solution

The empirical relation

\frac{x}{m}=k p^{\frac{1}{n}}

, is known as the Freundlich adsorption isotherm. Taking the logarithm on both sides,

\log \frac{x}{m}=\log k=\frac{1}{n} \log p \text{

If a following curve is plotted } $$ A plot of (x / m) versus p for the adsorption of a gas on a solid gives a straight line with slope equal to:
