A chemistry student wants to study the adsorption behavior of a gas on a solid surface. The Langmuir adsorption isotherm experiment is conducted at temperature T. After analyzing the data, the student finds that the maximum adsorption capacity (at saturation) is q moles of the gas per unit area of the solid surface. The student also determines the value of the Langmuir constant K, which is proportional to the affinity of the gas for the surface. Now, the student needs to determine the fraction of the surface that is covered by the gas molecules at a certain pressure P below the saturation
