Vedclass · Answer

(C) The Freundlich adsorption isotherm equation is given by $\frac{x}{m} = kP^{1/n}$,where $x$ is the mass of the adsorbate,$m$ is the mass of the adsorbent,$P$ is the pressure,and $k$ and $n$ are constants.Taking the logarithm on both sides,we get: $\log(\frac{x}{m}) = \log k + \frac{1}{n} \log P$.This equation is in the form of a straight line $y = mx + c$,where $y = \log(\frac{x}{m})$,$x = \log P$,slope $m = \frac{1}{n}$,and intercept $c = \log k$.Therefore,plotting $\log(\frac{x}{m})$ versus $\log P$ yields a straight line.

The Freundlich adsorption isotherm gives a straight line on plotting:
