WebbUnder these circumstances, the molecules of \(A\) adsorbed on the surface are in equilibrium with those in the gas phase and we may predict the surface concentration of A from the Langmuir isotherm, i.e. \[θ = \dfrac{bP}{1 + bP} \nonumber \] The rate of the surface decomposition (and hence of the reaction) is given by an expression of the form WebbThe maximal inhibition efficiency of 91.79% was obtained with the CLE at its optimum concentration of 0.4 gL−1. Adsorption of the CLE was found to obey the Langmuir adsorption isotherm and underwent both physisorption and chemisorption process. The kinetic and thermodynamic parameters were calculated and discussed in detail.
