Freundlich adsorption isotherm is a purely empirical correlationfor gaseous adsorbateswhere x is the mass of the adsorbate adsorbed m is the mass ofthe adsorbent P is the pressure of the adsorbate concentration incase solute rather than gas and k and n are empirical constantsfor each adsorbentadsorbate pair at a given temperature henceisotherm As the temperature goes up the constants k and n changeto reflect the empirical observation that the quantity adsorbedincreases more slowly and higher pressures are needed to saturatethe surface The function is inadequate at very high pressurebecause xm has an asymptotic maximum    See Answer
