In the curve of Freundlich adsorption equation, if the slop of the plot is zero, then extent of adsorption is

Freundlich gave an empirical relationship between the quantity of gas adsorbed by a unit mass of solid adsorbent and pressure at a particular temperature. The relationship can be expressed by the following equation:x/m =k(P)1/nwhere x is the mass of the gas adsorbed on mass m of the adsorbent at pressure P,,k and n are constants which depend on the nature of the adsorbent and the gas at a particular temperature.On taking logarithm on both sides of the equation,log(x/m​)=log(k)+1/n ​log(p)Here,1/n is slope and if its zero then adsorption is independent of pressure as1/n ​log(p)=0
