Question

derive gibbs adsorption isotherm

Answer 1

The resulting equation is the Gibbs adsorption isotherm equation: The Gibbs adsorption isotherm is an equation which could be considered an adsorption isotherm that connects surface tension of a solution with the concentration of the solute.

Answer 2

Answer:

At constant temperature, in the presence of adsorption, the Gibbs adsorption equation is dγ = −∑(ni/A)dμI = −∑ΓidμI, where (ni/A) = Γi is the number of moles of component I adsorbed per unit area and μI is the chemical potential of the surfactant solution.
