For adsorption of a gas on a solid, the plot of log $x / m$ vs log $P$ is linear with slope equal to ( $n$ being whole number)

Options:

Answer:

Solution:

According to Freundlich adsorption isotherm, at intermediate pressure, extent of adsorption $\frac{x}{m} = k P^{1/ n} or lo g \frac{x}{m} = lo g k + \frac{1}{n} lo g P$
plot of $lo g \frac{x}{m}$ vs log $P$ is linear with slope $= \frac{1}{n}$
