उत्तर
Explanation:
Freundlich, in 1909, gave an empirical relationship between the quantity of gas adsorbed by unit mass of solid adsorbent and pressure at a particular temperature.
`x/m= kp^(1/n) (n > 1)`
The adsorption varies directly. Where `x/m` = mass of gas adsorbed per unit mass of adsorbent particle p = Pressure of gas at particular temperature.
