The curve that best describes the adsorption of a gas x g on 1 . 0 g of a solid substrate as a function of pressure p at a fixed temperature is

Step-by-step solution

Variation of mass of gas adsorbed x per mass of adsorbent m with increase in pressure is given by x m ∝ p 1 / n (Freundlich isotherm) which is graphically represented by graph 2 .
