Choose an option

Show full solutionCorrect option: B
Correct answer
B1n

Step-by-step explanation

Freundlich gave a relation between the amount of the gas adsorbed per unit mass of the adsorbent (m) and the pressure (p). This is known as Freundlich’s adsorption isotherm.

As per Freundlich adsorption isotherm

xm=KP1nx=1n

Hence answer is 2
