Question

Adsorption of a gas on a solid surface follows the Langmuir isotherm. If \(\frac{ k_a}{k_d}\)=1.0 bar^-1 , the fraction of adsorption sites occupied by the gas at equilibrium under 2.0 bar pressure of the gas at 25 °C is 
( k_a and k_d are the rate constants for adsorption and desorption processes, respectively, at 25 °C)

• A. \(\frac{1}{4}\)
• B. \(\frac{1}{3}\)
• C. \(\frac{1}{2}\)
• D. \(\frac{2}{3}\)

Answer 1
