Consider non-dissociative adsorption. Assuming both adsorption and desorption are first-order processes, write down an expression for the coverage of an adsorbate as a function of time. The system is at a temperature T, there is only one component in the gas phase above the surface at pressure p and the saturation surface coverage is given by qmax. Assume adsorption is non-activated and that the sticking is direct. Hint: Start by writing d? (t) dt =? 0 d?(t) dt = r ads ? r des
