Is also applicable to second order reactions that may not be concerted reactions.
2.
The sulphanilamide can oxidise to a blue product with a first order reaction and it can form azo dye with a second order reaction.
3.
Contrasting with the classic Staudinger reaction, Staudinger ligation is a second order reaction in which the rate-limiting step is the formation of phosphazide ( specific reaction mechanism shown in "'Figure 9 "').
4.
Measuring a second order reaction rate with reactants A and B can be problematic : The concentrations of the two reactants must be followed simultaneously, which is more difficult; or measure one of them and calculate the other as a difference, which is less precise.
