Overall Kinetics for Ordering

Having confirmed that stages 1 and 2 correspond to the return of SRO to equilibrium via two processes, each obeying a first-order kinetic law, it will now be demonstrated that they can be depicted by a single relationship. This expression can be written as a convex linear combination. 

0i and O2 being the 6 function when Ei or E2 are used respectively and = AHi / AH2). It should be noted that is a measure of the excess vacancy
