Hi

Master plots method given in the following equation-1 is used to identify the reaction mechanism of the solid sate reaction.


equation:  g (α)/g (0.5) = p (x)/p(0.5)----1

where p (x)= exp(-E_a/RT)T²

p(0.5)=exp(-E_a/RT_0.5)T²_0.5

Basically its a comparison between theoretical and experimental plots.

In the equation-1, α=0.5 is considered as a reference point. what is the significance of the alpha (α) here? why the reference point is selected as 0.5?

Thanks
