Please derive Assume rapid equilibrium an equation when you have the following reactions
T <==> R
R + A <==> RA
RA + A <==> RA2
and the velocity comes from
RA --> R + P
Then v1 = k [RA]
and
RA2 --> RA + P (this velocity should be double, since you have two A bound)
Then v2 = 2 k [RA2]
Total velocity v = v1 + v2
Use nomenclature like MWC model
