Adsorption of a gas follows Freundlich adsorption isotherm. In the given plot, $x$ is the mass of the gas adsorbed on mass $\left(m\right)$ of the adsorbent at pressure (P). if $\dfrac{x}{m} ∝ {P}^{( 1 / y )}$ find the magnitude of $‘y’$ is ------.

Question

Adsorption of a gas follows Freundlich adsorption isotherm. In the given plot,

x

is the mass of the gas adsorbed on mass

\left(m\right)

of the adsorbent at pressure (P). if

\dfrac{x}{m} ∝ {P}^{( 1 / y )}

find the magnitude of

‘y’

is ------.

Correct answer: 2

According to Freundlich adsorption isotherm,

\dfrac{x}{m} = K \times {P}^{1 / n}

log\dfrac{x}{m} = logK + \dfrac{1}{n}logP

m = \dfrac{1}{n} = \dfrac{2}{4} = \dfrac{1}{2} ⇒ n = 2

So,

\dfrac{x}{m} = K \times {P}^{1 / 2}

Therefore, value of

'y'

is

2 .
