Definition Of

Close examination of the concept of the rate-determining step (RDS) shows that there are two types of RDS depending on the definition of ‘rate’. One is represented by the highest peak of the free-energy diagram of consecutive reactions and holds true where the rate is defined in terms of the concentration of the first reactant. The other is represented by the peak showing the maximum free-energy difference, where the free-energy difference is the height of a peak measured from the bottom of any preceding troughs, where the definition of the rate is in terms of the total reactant concentration including intermediates. There are no criteria a priori for selecting one of them.

Step Transition

ABSTRACTIn the Nb-rich Nb-Fe(Co,Ni) multilayered films, two metastable crystalline (MX) phases of hep and fee structures were formed by room temperature 200 keV xenon ion mixing. The phase formation was through a two-step transition, Le. a first shearing of bcc—>hcp and then a sliding of hep—>fcc. The free energy curves of the observed MX phases were calculated and included into the free energy diagram together with those of the terminal solid solutions, the amorphous phase and the equilibrium intermetaШc compounds. An independent comparative thermal annealing experiment was conducted with the corresponding as-deposited multilayers and the results certified the emerging sequence of the MX phases being exactly the same as the calculated diagram predicted. Moreover, a crystallographic model was figured out for the bec—>hcp—>fcc transition and the resultant lattice parameters agreed well with the experimental ones.
