(C) The Freundlich adsorption isotherm is given by the equation: $\frac{x}{m} = k p^{1/n}$.Taking the logarithm on both sides,we get: $\log \left( \frac{x}{m} \right) = \log k + \frac{1}{n} \log p$.This equation is of the form $y = mx + c$,where $y = \log (x / m)$,$x = \log p$,slope $m = 1/n$,and intercept $c = \log k$.Therefore,plotting $\log (x / m)$ on the $y$-axis and $\log p$ on the $x$-axis yields a straight line with a positive slope of $1/n$ and an intercept of $\log k$ on the $y$-axis.

Which one of the following graphs represents the Freundlich adsorption isotherm?
