Vedclass · Answer

(C) The Freundlich adsorption isotherm is given by the equation $\frac{x}{m} = kP^{1/n}$.Taking logarithms on both sides,we get $\log(\frac{x}{m}) = \log k + \frac{1}{n} \log P$.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 $\log(x/m)$ vs $\log P$ gives a straight line.
