What is an adsorption isotherm ? Write the equation of Freundlich adsorption isotherm.

Explanation

Adsorption Isotherm : The variation in the amount of gas adsorbed by the adsorbent with pressure at constant temperature can be expressed by means of a curve known as adsorption isotherm.
`to` Freundlich adsorption isotherm equation is `x/m=k .P^(1//n)`
x=mass of the gas adsorped
m=mass of the adsorbent
P,K and n are constants.
