2 . The adsorption of a certain substance, X , follows a Langmuir isotherm. Saturation coverage of the material is 8 times 1 0

2. The adsorption of a certain substance, X, follows a Langmuir isotherm. Saturation coverage of the material is 8\times 10-10 mol/cm2 and =5\times 107 cm3/mol (assuming ai = Ci). At what concentration of X will the electrode surface be half covered? Sketch the adsorption isotherm of the substance. At what concentrations of X will the linearized isotherm be valid to ~1%? Under linearized conditions and taking D =10-5 cm2/s, how long after immersion will be required for the surface of a plane electrode to attain half of the equilibrium coverage? How long will be required to attain half of equilibrium coverage if the solution is stirred and m =10-2 cm/s?
