Question

The Langmuir adsorption isotherm is given by $	heta=\frac{k_p}{1+k_p}$, where $p$ is the pressure of the adsorbate gas. The Langmuir adsorption isothem for diatomic gas Ay undergoing dissociative adsorption is

Professor PC Thomas Classes · Answer

For dissociative adsorption of diatomic gas $A_2$, the isotherm modifies to $	heta = \frac{(kp)^{1/2}}{1 + (kp)^{1/2}}$.
