Q. Which equation represents Freundlich adsorption isotherm (physical adsorption is basis of this theory)?
A) $\frac{x}{m} = K(P)^{1/n}$ where $x$ is amount of gas adsorbed on mass $'m'$ at pressure $P$
B) log$\frac{x}{m} = \log{K + \frac{1}{n}\log P}$
C) $\frac{x}{m} = KP$ at low pressure and $\frac{x}{m} = K$ at high pressure
D) All of the above
Explanation
(d)
These are different forms of Freundlich equation.
