Freundlich isotherm is related with the pressure of gas adsorbed, as follows

x

m

=k.p1∕n
where,

x

m

= amount of gas (x) adsorbed over the surface of mass (m).
pressure of gas
k = freundlich constant
Thus, value of ' n ' is always greater than 1 and therefore value of 1∕n lies between 0 and 1 .
