In an adsorption experiment, a graph between $\log (x/m)$ vs $\log P$ was found to be linear with a slope of $45^{\circ}$. The intercept on the $\log (x/m)$ axis was found to be $0.3$. The amount of the gas adsorbed per gram of charcoal under a pressure of $1 \ atm$ is:

$CO_{2}$ gas adsorbs on charcoal following Freundlich adsorption isotherm. For a given amount of charcoal,the mass of $CO_{2}$ adsorbed becomes $64$ times when the pressure of $CO_{2}$ is doubled. The value of $n$ in the Freundlich isotherm equation is $......\,\times 10^{-2}$. (Round off to the Nearest Integer)

When $H_2S$ gas is passed through an arsenious oxide solution,an arsenious sulphide sol is formed. The charge on the particles is due to the adsorption of .......

Point out the wrong statement: Physical adsorption is characterized by

Adsorption of a gas follows the Freundlich adsorption isotherm. $x$ is the mass of the gas adsorbed on mass $m$ of the adsorbent. The plot of $\log \frac{x}{m}$ versus $\log p$ is shown in the given graph. $\frac{x}{m}$ is proportional to:

Which of the following is true for spontaneous adsorption?
