For Freundlich adsorption isotherm, a plot of (x / m)(y - axis) and...

$\left(\dfrac{x}{m}\right) = k\left(P\right)\dfrac{1}{n}$

$\log \left(\dfrac{x}{m}\right) = logk + \dfrac{1}{n}logP$

Slope $= \dfrac{1}{n} = 2$

So $n = \dfrac{1}{2}$.

Intercept $⇒ logk = 0 .477$

So $k = Antilog\left(0 .477\right) = 3$

So \left(\dfrac{x}{m}\right) = k\left(P\right)\dfrac{1}{n}$</p><p>$3{\left[0 .04\right]}^{2} = 48 \times {10}^{- 4}
