The correct option representing a Freundlich adsorption isotherm is

If $x$ gram of gas is adsorbed by $m$ gram of adsorbent at pressure $P$,the plot of $\log \frac{x}{m}$ versus $\log P$ is linear. The slope of the plot is: ($n$ and $k$ are constants and $n > 1$ )

Assertion : In chemisorption,adsorption first increases with temperature and then decreases.
Reason : Heat keeps on providing more and more activation energy.

The number of statement/s which are the characteristics of physisorption is
$A.$ It is highly specific in nature
$B.$ Enthalpy of adsorption is high
$C.$ It decreases with increase in temperature
$D.$ It results into unimolecular layer
$E.$ No activation energy is needed

If the initial pressure of a gas is $0.03 \, atm$,the mass of the gas adsorbed per gram of the adsorbent is $...... \, \times 10^{-2} \, g$. Based on the provided graph,determine the value.

In the adsorption of acetic acid on activated charcoal,the acetic acid is an
