Identify the incorrect statement.

In Freundlich adsorption isotherm,the value of $1/n$ is

Adsorption of a gas on a solid adsorbent follows the Freundlich adsorption isotherm. If $x$ is the mass of the gas adsorbed on mass '$m$' of the adsorbent at pressure $p$, then from the given graph, the extent of adsorption is proportional to:

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

$10 \, mL$ of $1 \, mM$ surfactant solution forms a monolayer covering $0.24 \, cm^2$ on a polar substrate. If the polar head is approximated as a cube, what is its edge length?
