2.13.1.2 Excess oxygen i.e. high pO₂

At large oxygen excess, we can assume that

[]

(2.60)

In such a situation, from (2.51), we get

(2.61)

and from (2.53), we get

[] =

(2.62)

Now, from (2.52), we get

(2.63)

Now combining (2.61)-(2.63) and using (2.60), we get an important condition i.e.

(2.64)
