Kinetics of Overall Reactions for Ammonia Synthesis

It is assumed that catalytic reaction kinetics is obtained on perfect and imiform surfaces (Langmuir surface), in which all active sites are of the same nature of 

1 General relation between overall reaetion and elementary steps 

Supposing that a reaction includes with n elementary steps, and each one with a stoichiometric number 7, following Temkin method (1971), we can write  

With the quasi-stationary approximation, the net rate v of the overall relation is equal to the difference between forward and reverse rates of each step with the suitable weighing of the stoichiometric number of that step  

Substituting Eq. (2.80) into (2.79) gives a general relation of Temkin
