How to calculate the maximum surface excess concentration?

17 November 2023 0 7K Report

I plotted the surface tension as a function of my surfactant concentration . Now, I'm trying to calculate the maximum surface excess concentration by applying the Gibbs adsorption isotherm to the surface tension data, but I don't know how to use Eq.

Γ=−1/RT(δγ/δlnC).

How to derive the expression in parentheses??
