Identify the factors which favour the physical adsorption from the following.
$(I)$ High surface area
$(II)$ Low temperatures
$(III)$ High temperatures
$(IV)$ Low pressures
$(V)$ High pressures

$A$ plot of $\log \left( \frac{x}{m} \right)$ vs $\log \, P$ for the adsorption of a gas on a solid gives a straight line with slope equal to

Froth floatation process for the concentration of sulphide ores is an illustration of the practical application of

Adsorption of gases on a solid surface is generally exothermic because

If $x$ is the amount of adsorbate and $m$ is the amount of adsorbent,which of the following relations is not related to the adsorption process?

The correct option$(s)$ related to adsorption processes is(are):
$A$. Chemisorption results in a unimolecular layer.
$B$. The enthalpy change during physisorption is in the range of $100$ to $140 \ kJ \ mol^{-1}$.
$C$. Chemisorption is an endothermic process.
$D$. Lowering the temperature favors physisorption processes.
