A dsorption of gas follows Freundlich adsorbtin isotherm. In the given plox ,x is the mass of the gas adsorbent at pressure P. is propotional to:
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
As we know that:
From the graph
Logarithmic graph of Freundlich isotherm -
The slope of the straight line gives the value of 1/n. The intercept on y-axis gives the value of log K.
