Application of absolute rate theory to bimolecular surface reactions

4 APPLICATION OF ABSOLUTE RATE THEORY TO BIMOLECULAR SURFACE REACTIONS [Pg.13]

The formulation of rate expressions for surface reactions has been described in detail by Laidler [42]. In this section, we confine our attention to its application to the derivation of rate expressions relevant to hydrogenation reactions. Again, it is necessary to specify the mechanism in order to derive relevant rate expressions. [Pg.13]

For a bimolecular reaction proceeding by an adjacent site (Langmuir— Hinshelwood) mechanism [Pg.13]

Equation (15) is of the same general form as that derived from the simpler [Pg.13]

If reactant A is strongly adsorbed and B weakly adsorbed such that bA 1 bB, eqn. (15) simplifies to [Pg.14]
