Many surface reactions require the adsorption of two or more different gases. For the case of two gases, assuming that the adsorption of a gas simply limits the number of surface sites available for adsorption, derive expressions for the fractional coverage of each gas.$\backslash$table$[[(1-K_1{P}_1-K_2{P}_2)$ this is what I have now. Can you help me fill out the rest of the blanks?
