A chemistry student is studying the adsorption of a gas on a solid surface using the Langmuir adsorption isotherm. The student knows that the maximum adsorption capacity (θ_max) of the surface is 0.5 mol/L and that the equilibrium constant (K) for the process is 0.02 L/mol. The student is asked to calculate the fraction of the surface covered by the adsorbate when the gas pressure is 2 atm at the temperature of the experiment.
