Concept:

Freundlich adsorption isotherm:

Freundlich gave an empirical relationship between the quantity of gas adsorbed by a unit mass of solid adsorbent and pressure at a particular temperature.

Taking log on both sides, we get,

We know that, the formula of slope is:

In the formula, the slope is 

Therefore,

From graph, the value of slope is:

The Freundlich equation is:
