Adsorption of a gas ( $A$ ) on an adsorbent follows Freundlich adsorption isotherm. The slope and intercept (on $Y$-axis) of the isotherm are $0: 5$ and 1.0 respectively. What is the value of $\frac{x}{m}$, when the pressure of the gas $(A)$ is 100 atm ?

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
