According to Freundlich, there is an empirical relationship between the amount of gas adsorbed by a unit mass of solid adsorbent and the pressure at a given temperature:
‌

x

m

=k⋅p1∕n‌‌(‌ for ‌n>1)
Here, x represents the mass of gas adsorbed, m is the mass of the adsorbent, and p is the pressure. The constants k and n are specific to the system being examined.
By taking the logarithm of both sides of the equation, we have:
log‌

x

m

=log‌k+‌

1

n

‌log‌p
To verify the validity of the Freundlich isotherm, you can plot log‌

x

m

on the y -axis and log‌p on the x-axis. If the plot forms a straight line, the isotherm is valid. If not, it indicates a lack of alignment with the Freundlich equation.
